Really got to stop

I really got to stop fucking my ex , but i can’t help it’s he’s so hot best sex ever like seriously. But I keep telling him this doesn’t mean we getting back together, he still holds out hope that I’ll change my mind we broke up for very good reason but he still thinks he can win me back if he’s hang on and gives me the dick and everytime I tell him no this is just sex he says ok then afterwards he’s tell me he loves me 😑 I got to stay away from him he very attractive like he can have anybody he wants but he says I’m the only one and he will fix his life and get his shit together for me but I just don’t trust him he was hiding his drug problem from me for too long then he said I’ll go to rehab for us then only made it 19 days then came home so I was done with him
