i lost my ex cause i was beta, did everything wrong. she went to another man cause of my behavior and now she is in love with him. So, be in NC, dont beg, cry or stalk her, believe me, you will push her away as i did. Now after few month, i deleted her from my FB, delete her phone number and pick up few girls. Among them i found one, i like her a lot and probably i will be in LTR with her, so if she don't contact you, you should move on ...
