Very confused about this guy

I've been seeing this guy for about 7 months now...like almost every weekend,and then some....the sex is amazing and I thought we were getting very close emotionally...he is kind of dominant, and I like that...but when I texted him last weekend (thought for sure I would see him cuz we have every weekend) I texted "Hey u, whats up"? and he texted back, "not u"...my heart sunk....the weekend before was awesome...so, I was very confused by his response...I texted back,"what does that mean"? and he texted back "nothing.Here hownew Ph fat fk:-)k:-) ingerz a bout u"....wtf does that mean??? I haven't heard anything from him since...and I have NO idea what to think, or what to do....I didn't mean to fall in love with him, but I have...and I've fallen hard...anybody have any advice? or anything? I appreciate any input....thanks...

Well right now all i can tell you and ask you is Have you spoken to him ever since . becuase mybe someone told him that you cheated on him and he loves you so much or that his parents found out about sex or He is a little frreaked out about the sex and feels uncomfortable see what i just did i just i thought of all the possibilities and if you message me back the answers and whats happening me now then i can help you more

I haven't spoke to him since, and I'll probly just wait til he contacts me...cuz I don't really know what to say to him...his parents have nothing to do with anything,and we never told eachother we wouldn't see other people,and I'm certain the sex didn't freak him out...but thanks for trying to help...
