What is his deal?

Ok, so if you need to know the reasons for which he claims to have broken up with me then I will tell you but for now my question is this: What is my ex's deal with breaking up with me and then when I give him his complete and utter freedom (literally, when someone breaks up with me I break all contact: no calls, no texts, no e-mails, nada) he decides on a whim he wants to get back together and then on another whim he wants to break up just to want me back again? Why do that to me and to himslef, frankly? And what is up with breaking up with a girl but then expecting her to still give you all the benefits of being a committed relationship without actually giving her one?

You know that your answer to this question is a simple one. If the guy is giving you that much of a runaround, cut him off and don't keep giving him the impression that he can waltz back into your life at whatever time of his choosing and then waltz back out and keep repeating that cycle. Holding yourself out for him is just holding back your own life, while he probably tests the field before coming back to you.

So I say you need to end that. However, if you feel strongly for him and you really want to be with him long term you need to make it clear that you're giving him ONE opportunity and if he walks out again, there won't be another.

He does it because you tolerate it.

maybe for sex?

when u say he wants to break up AGAIN... why r u taking him back?

Ugh, you're all right. . .yeesh.

for his ego, he wants you to be sitting at home crying over him and his probably feeling unless.So he keeps getting back with you trying to see what your deal is, trying to make a big enough impression to create some drama in your life. Just cut him off.

Because you're nieve enough to take him back every time.

Cut him off for good, and don't buy any of his "oh baby I want you back" bullshit, because chances here, he's just using you for a quick booty call and leaves when he's done.

Cut your loses move on. If he contacts you in the future tell him he had his chance and blew it. In the end you'll be much happier with that loser out of your life.
