Hi, I'm a 23 y.o female who met a wonderful guy 6 months ago. We both fell for each other quickly and moved just as fast.  4 months into the relationship I find out he is in a very unhappy marriage and wants out of the marriage.  I was shocked and unbelievably depressed I listened to my friends and tried to move on regardless of his sincere feelings for me but it's hard to move on when that person became your best friend and he won't leave you alone, and I wasn't sure I wanted him to leave me alone.  [...]

This is way too much for me I would really like to keep him in my life just as friend maybe date casually but deep down I know he's not the one for me, so why do I get depressed when I'm away from him even though he drives me crazy??  What do I do to get my life back on track?? Please help asap. Thanks.
