Is it worth sending a guy who rejected me a message after 6 months? getting my lick back?

We talked for about a 2 weeks and had one date … I just felt very hurt by his actions and I’m still having a hard time getting over it…

It wasn’t about the rejection itself but just how bad and invaluable I felt… it really hurt

After ghosting he did give closure but it was still quite hurtful

I gathered some information on him and I want to get my lick back

Is it worth it?
