Just really need advice?

Ok so here is the story. I met a neighbor of mine on june 12 and was invited over his place for drinks. I didn't have a babysitter so i couldn't. The next day i was out on a walk with my son and he was headed toward the park so we started talking and getting to know each other. He kissed me. We exchanged numbers. We started texting and he asked me to meet him for a good night kiss but i didn't. I got a hold of the babysitter the next night and i went over his place where we had mind blowing 4 different times. Then he walked me home. The next day he didn't talk to me at all then the day after he said nothing just walked right up to me and kissed me. We met the next day for a hot makeout session near my laundry room. Then he again didn't talk to me the next day. Then after he text me randomly and said he was going to stop by and see me. We made it clear we'd be just friends with benefits. The day he stopped by we had another hot moment of pion. I said it sucks sleeping alone and he said well you better be sleeping alone and i said why im not your gf you wanted it that way and then everything changed. He stopped texting completely and we slowly came to a halt on . We stopped talking for 2 months and 4 weeks ago he was heading to the gas station and i was on my walk and he walked up to me and kissed me. We walked to the park and spent the majority of the evening snuggled up. Now he is back to not texting or talking and he keeps getting this attitude when we're together. He is usually excellent about kissing me goodnight but not tonight and it really hurt my feelings. I've grown to love him deepy.
