Forget what others think. It is only about what you want and believe. I can tell you from experience my own mother strongly dislikes a few of my Ex's (who are friends) but he view of them changed with time as they proven themselves to be good people (just not the one to be with me). If you love yourself others will follow and if they dont they will go on their own. You just keep the good vibes up.

Dude trust me this is the one place everyone understands you. From my experience your best bet is to step back and look at yourself. Are you happy with yourself? If not what can you do for that? Reason being that it's all about you. How you think and feel. And from what it seems you aren't to happy and you are looking for that in everyone else but you. Don't worry about how she sees you, worry about how you see yourself. When you honestly see the good in you so will she.

I'm currently married and my wife left. Things were headed down hill. And I tried all the normal stuff that everyone tried (beg, cry etc.) It wasn't until I looked at how I saw myself and worked on it that her view of me changed. She told a friend recently that she is so confused by my attitude because she was expecting me to throw tantrums and stuff. She likes how I've turned out. Not back with her (yet) but I'm in no hurry. I'm enjoying the process and you'd be surprised at how things work. While learn LOA A lot has come my way (job promotion especially). It's all about you, everything else follows.

Hope this helps and hold your head high!
