So there’s this guy (advice?)

So I’m currently talking to someone names Callum and we send nudes from time to time...I’ve dated him and I want him to go out with me again 🙄

But idk how idk how to leave him wanting more and he always has a dumb excuse not to come meet me unless I bribe him with sexual gestures which he still don’t turn up to...

I’ve told him how I feel before but it just goes back to normal after 2-3 days what do I do any advice?
