Should I tell a guy I’m going on a date with someone else?

Been seeing this guy on and off for a couple of months, he’s a jerk and I keep hoping he’ll be abit more emotional or into me personally but he’s not.

We’ve met up twice, once a proper date and the other sex. He wants to meet up tomorrow again for sex, which I don’t mind if he made an effort to talk to me but the last two days he’s sent me 2-3 texts.

I said to him that it’s impossible to have a normal conversation with him (he takes ages to reply unless it’s about sex) to which he said he isn’t in the right head space and that he’s sorry and hasn’t texted me since, but has been online.

I know he’ll text me tomorrow to meet up, but now I don’t really want to.

When he texts should I just say I’ve made plans to see someone else? I feel like I want to be a bitch and be like “f*ck you, I’m seeing someone who gives a shit about me”, but I know that’s not right haha

He’s just pissed me off so much over the past couple of months, and I’ve given him so many chances to be a good guy who’s interested in me (I know I shouldn’t have given him more than one chance, please don’t come at me).

I might just block him, was supposed to see him tonight but I don’t want to give him the satisfaction
