boys r confusing

Okay so I've been on and off with this guys for so long and he did something horrible and we didn't talk for a while and then he apologised on my birthday (1st of December) and we haven't talked since but today he snapchated me and wanted to hang  and have sex which made me mad because I kinda thought he respected me and actually meant what he said when he said sorry for using me for sex before but yet here he is again trying to get sex from me again but I'm proud to say I stood up for myself  and said no after all he put me through I said no it may not seem like a big deal ahah but I find it hard to say no and I genuinely cared about him still do abit but I knew he was using me like  he uploaded a photo of him and this girl and they are clearly taking so they must've had a fight or something and he just thinks he can come to whenever he wants anyways sorry if this doesn't make sense but this boy has put me through a lot and I'm just proud to say that I think I'm finally over and I feel so happy and I'm so proud to have finally stood up to him & realised how much of a horrible human he is.
