When are you going to learn that those moments of what you call "relief" are very temporary? Do not allow your emotions to lead.
I can almost assure you that she's not telling the complete truth. It does no good to pressure her.
Do you want her back b/c she feels sorry for you? What if she came back b/c she was scared of what you might do? Maybe if she was pressured enough, would that work for ya? Ask yourself if you want her back under any reason, other than she's in love with you?
Pressuring her certainly does not make you very attractive. Neither does being drunk. The board s filled with how others got past this same type situation, and many of the men tossed the bottle.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
