Letting go.

How can I just let go? I’ve been seeing this guy for awhile and we had sex and he’s ghosted me it’s been three days now. He’s done this before. Before I always see him he we text and he act like he wants to see me but when I see him he barely looks at me , he doesn’t speak , we have sex and I just go home bc he don’t really say nothing . He tells me that’s just his personality but I don’t know. How do I cut him off without missing him? How do I have the strength to not respond when he text me. If I block him I’ll feel bad. I’m just depressed. Everytime I check my messages it says I’m on delivered for 3 days. Advice?😞
