Getting bothered

I genuinely don’t know why it bothers me so much. When I was extremely drunk, I met up with someone from Reddit. We ended up having sex. Now that I’m sober I have absolutely no attraction. But I keep getting texts. And it’s 90% of the time hitting on me. Here is what I did. First I just ghosted. After awhile, I get a text saying something like “I’m coming to your house if you don’t answer”. So I did but I very clearly said I want to be alone rn my life is shit. A few days later and I’m still getting texts. I’m at this point where I don’t know if I should block, go off or continue to ignore. Yes I feel bad but equally, you really shouldn’t have had sex with me when I was drunk. At the very least don’t expect me to have feelings after.
