Kwan1, I've been married X 2 & am currently married the the second woman who happens to be the "love of my life". Sounds like you are feeling sorry for yourself because you have strong feelings for someone else who's not available to you now.
When I met my 2nd wife (& I really love this woman 99.9% of the time), I had a live in, & I tried to date current wife (who I'd just met) and I lost her because she was very offended that I'd ask her out while I had a live in. I felt sorry for myself for several months & eventually ended the live in relationship. Then a few months later I hooked up with current wife (the one I gave up on) who also had just gotten out of a relationship.
I'll always think of ending my live in relationship as a leap of faith, because I didn't have a safety net relationship to fall back on (it sounds bad, but that's the way I was thinking), & I ended up with the love of my life, the woman who took my breath away when I first saw her & made me stutter for 6 months after we started dating...
The leap of faith worked for me, & I'd do it again. Don't settle or you'll regret it, and you'll grow to resent your current relationship because it reminds you of your own fear of rejection, change, etc...
