Am i the only one??

So I was in a fwb thing that lasted for more than a year and suddenly he just stopped talking to me but I respected him and I didn't talked to him neither like I kind knew it that it was coming, of course he broke my heart because I had feelings for him and he knew but it didn't bother him so we kept our thing for more than a year..like six months ago that was when he stopped talk to me and our thing end up there.

And last week he send me a message telling me that he wanted to out with me and today we were talking and he told to go buy condoms so he let it clear that he wanted sex again..of course I didn't go because I don't want to go through that again... I'm just wondering why people and man like this exist..
