Advice please..!!

I recently made a post about my situation this is just an update I took everyone's advice and acting on it. Those of you who don't know my story well, I will fill you in, I met this guy online yes I'm embarrassed about it he told me he wanted a relationship that's what I wanted too we ended up sleeping together it wasn't planned it just happened I felt horrible because I can't just sleep with someone casually I'm the type who has to be committed, he told me he wasn't ready for a relationship but was attached to me I felt horrible because I actually had feelings for him I didn't understand how we can get along and have such great chemistry and great sex and he just didn't want to be with me relationship wise it hurt me a lot, I recently put my story on here and great advice I acted on it, it took me awhile but I did it I told him I couldn't just keep sleeping with him with no commitment and I do have feelings for him and I knew were we stood and I know he can't offer me what I want and I wasn't trying to force him into anything either but I just can't see him or stay friends I always walked away feeling a little hurt. His response was he didn't want alienate me but he isn't ready for a relationship and he will never forget me and told me to keep his number and if I have a change of heart to text him, it just hurts me he really didn't care I really liked him. My question is how can I deal with this I'm hurting and I'm trying not to text him and just be strong and move on advice would be nice.
