So I'm back with my ex... and I have to say, I feel like the positive feelings I had for her feel so much less pressing. I don't know what I really feel about her, and it almost feels like I'm trying not to get to involved.
Anyways, she was gone for a week and she's coming home... I stayed faithful, I didn't even do coke... but it doesn't really psyche me up that much that she's coming home. I almost feel like I'd rather just get trashed than fuck her. I don't know what to do. Should I get out of this? ToTSE, make my decisions!

If you're just not feeling all that much for her, then perhaps it is time to say that it was right to break up in the first place.

However, given time you might find those feelings re-emerging and to break up with her again could be a regret.

Think carefully.

Generally speaking, these feelings are usually the first step before you realize that you just don't want to be with the person anymore. Give it time, and if you see that the feelings you have towards her aren't to that point that they once were, and you have a general shroud of apathy when it comes to the relationship, it might be time to say goodbye for good.

If you truley and honestly don't feel the same way about her that you once did, you need to tell her so she can move on with her life instead of being in a un-even relationship. Don't let her find out on her own, and don't just act like an ass so she'll stop loving you and you can avoid a confrontation.
