you absolutelly SHOULD NOT go back with him. he treated you like a piece of sh*t, what garantee do you have that he is not goint to treat you like that again? if you go back with him then he surely is going to dump you again for another girl.  never allow ANY ONE to take advantage of you. people are not objects you throw into the garbage once you get tired of them. i´ve never been in a relationship but i had this similar situation going on in which my friend was being very promiscuous and i told him to stop because he was worrying me and he told me i was reacting way too dramatically to things and that he didn´t gave a flying f*ck about the whole situation. i ended our friendship because it was obvious that he didn´t care about my feelings. i loved him so much, and considered him to be my soulmate, my other half, my twin, but i never asked him if he felt the same way about me. after i "broke up" with him i felt very vulnerable and empty, i felt so frail. but then i told to myself "do you really want to be friends with a guy who thinks you´re a weakling and doesn´t care about you? HELL NO!". so far i´ve gotten over him, but deep inside i´m still hurting.  but i´ve got to move on with my life and forget about him, even if i have to force myself to do it.

You said "he didn't seem to be very into her", but it's also true that he doesn't seem very into you either. 

he's just being selfish. by contacting him every now and then, you keep bringing back the feelings which is preventing you from moving on. Just stop talking to him and you will finally be able to find someone you who won't leave you for someone else. he didnt break up w/ his girlfriend for you, he had some other reason. but, he knows that you still love him so he's probably just using you as a safety net. just leave him be and look for another fish in the sea. =D

It's hard, but I think it's best to pull away.

Dang.  He sounds pretty manipulative to me, like he's somehow expecting you to relieve him of the guilt he suffers for not being good to you.  Sister, that's not your job.  He should feel guilty, and it should push him to learn how not to be that guy any more.

You asked what he wants from you?
It sounds to me that all he has wanted from you is a friendship all along and because you have continued to correspond you have provided him with just that.
Now that his relationship has ended he would like to continue that friendship with you but you want more and he perhaps is feeling bad about it.

However to release his own shame for leaving you for another woman he apparently has never been able to let go of he has now basically given you an apology in his own way which he should have done two years ago but did not.

I would like to remind you once again it was TWO years ago and you are dealing with a guy here.

By him saying he is not going to bother you that is his way of saying perhaps you BOTH need to move on because your relationship is a sour one and always was because you unfortunately crossed the line.

There really was no need for you both to be corresponding between one another during that two years unless he was sincere in HIS FRIENDSHIP with you.

You on the other hand have admitted you were corresponding out of selfish reasons.
In hopes he would break up with his new girlfriend.

In a way is that not doing the same thing he did to you?
What if he had left her for you?
Where would that have left his girlfriend?

Moving back to his latest correspondence with you.
He said he wished there was something he could have done for you and that you could have relied on him or he could have helped.

This all sounds to me like he is trying to help you with closure as well.

Many women do not get this opportunity and again it sounds like you want your cake and eat it too.

I would take this opportunity to walk away if you have not already.

That is probably the best thing for you and worst and best thing you could do for him as well if you understand what i mean.

It is a win win situation for you because you will come out on top.

-stood up at the alter

i think its such a bastard. its time to let this guy out of ur life

leave him to his wallowing i think that maybe he doesn't realize how much pain he put you through and ur going to have to show him...jk

but really stay away things like this always turn out bad i was just heartbroken and i can tell u right now i'm done. although i don't like to b single.

it saddens me that you miss him so much that you refered to him as your "boyfriend" and not your "exboyfriend" in the beginning.

screw him, he fucked you over.  now get your life back.  i think you should make him hurt a little.

This is so hard.  It is strange how love and mistrust can seemingly exist for those with broken hearts, but please carefully consider what entering a relationship with him would be like.  Everyone deserves to be in a relationship with someone they can trust.  A deep and committed relationship isn't just "all you need is love."  Trust is a huge part of the foundation.  Good luck!

What he wants from you is something for nothing. He wants your support, encouragement, and company, without having to give you commitment, or be trustworthy.
A lot of the commenters above are saying that you should be friends with him- I think that's a bad idea. Yes, some relationships can devolve into friendships afterward, but I think the ones that are most successful doing that are the ones that weren't  that serious in the first place.
You have too much invested in this guy to remain in contact with him. If you want to move on, you need to stop talking to him.

honestly that email has no sort of clue whatsoever of what he wants. i think it doesnt b/c he doesnt know what he wants. reminds me of my parents actually...he knows that u had deep feelings, so you have to make sure he doesnt take advantage of that, meaning he knows ur their evrytime he fucks up; he can break up with u for someone else and knows your still pining and knows that when it doesnt work out with the other girl, you'll be there arms open waiting. i guess u can say i been in a similar relationship, and i've found someone who makes me happy....now my ex is the one shitting bricks, b/c he realized i was the best thing to happen..live life for yourself until u find someone...and if down the line, u KNOW he truly realizes how much he messed up , and your strong enough to get back with him and know if something happens you can handle it emotionally, then go for it..best of luck=)
