I do need some understanding here, because I really have nobody to talk to about this situation.
I get this too. Several of my close girlfriends are single and have never been in a serious R. Others thought I should have walked without looking back at the beginning. My mom divorced my biological father because she found out he was cheating so she was on the "walk now" bandwagon and also ends up making everything in my life a competition with what she went through. So not helpful!
Only here have I found people who (unfortunately) understand what I'm going through.
So vent away. Journal your thoughts and feelings. Ask questions, ask for support or advice, whatever you need.
If you love somebody, set them free. http://tinyurl.com/2empx2g
