<human>: Been friends and 2 1/2 years ago we started to date each other.  Early on, he told me he wasn't ready for a committed relationship but wanted to take it slow & see what happened.  I had a bad divorce & was okay with that.  At the time, he was separated & has a child & is now divorced 2 years.  We took it slow and things seems to progress & I have become a part of his son's life.  I love that kid like he is my own.  As time has gone on, I don't see him committing to me & I feel stuck.  I love him but I don't think he loves me the same way.  His ex-wife also just broke up AGAIN with her bf & has cast her net to see if he will come running & get back together (he did some other times that he doesn't know I am aware of)  I am sick of feeling like this but when I start to distant myself, he chases & makes me feel like I am been ridiculous.  Maybe I am but when I try to lock him down on the relationship status, he blows cold or disappears.  It is making me crazy.  I have never been able to cut people out of my life & need advice on what to do.
