feel awful, shall I get rid of this idiot??

First of all I feel awful, like I feel like crying. I've been talking to a guy for a while and everything was great, he kept messaging me making all the effort too. Never liked someone like this, I came away for 4 weeks to see family abroad and he was fine. I haven't been work anyone else!! I have sent him alot of photos of like my bum and boobs before like cheeky tease pics, we always have. Anyway lately he's being a right TWAT, I feel like I annoy him if I message him?? Once I confronted him and he was like ' no no I do like you, of course I'll see you when you are back) .. Anyway it's been 3 days and he's not bothered to message me, I sent him one first saying ' are you okay babe' and he oh read and ignored. And he's seen all my snapchat story's, and I've seen him on Facebook various. He dosent rally like me does he?? I never normally like people and him it felt different. But now I feel sad and hurt, shall I get rid of him! Been a prick so many times but this time,
