Why do men say they want a relationship but really thats not what they want?

I’ll try to make a long story short, I attended Lincoln Tech for about 2yrs where I befriended this guy. I thought he was cool and he became my “go to” person when I had questions about guys we became really close. Fast foward to the summer of that yr, he graduated and threw a party to celebrate I was invited of course, something happened and the police ended up shutting the party down. I was leaving and i bumped into him on the way out i started to say goodbye, we got to talking and he revealed that he had feelings for me and that he wanted me to be his girlfriend.

I guess you can call it me being stupid idk he SOUNDED so sincere. Being that he knew about all of the horrible things id been through with my sons father i didnt suspect a hidden motive, he asked for a kiss one thing led to another and you know the rest. it went on like that for the rest of the summer, throughout the summer he kept expressing how much he wanted me and wanted to be in a relationship with me…anyways fast foward a yr we had lost touch with each other and recently ended up bumping heads again

we hopped right back on the path we were on but after a session i asked him exactly what was i to him and he told me he didnt know. He said that he didnt know how to label us, I confronted him about all that stuff he was saying over the summer and he said he only said it because he was considering it. ( yea right)
I tried to end the friendship and he’s insisting on us being friends but since i told him that means we wont be having sex he’s stopped calling me and wont return anyof my calls…why is this??
