STOOOOOOOOOOOOOOOOOOOOOOP. You are allowing him to use you. Have you heard of "Having his cake and eating it too"? Have you heard, why buy the cow, when you can get the milk for free". If you don't respect yourself, then most men won't either.
You are way to old to be acting like that... Even if he wanted sexual intercouse with you. He doesn't want to marry you, so why would he claim you. I guess you guys are Friends with Benefits(fwb). LOL. I thought that was a new generation life style in sin. I guess I was wrong.
Please respect & LOVE yourself. Eventually, you will find someone who LOVES you and will make you priority in his life.
God Bless you and good Luck...I hope that helps.
