What Do I Do?

I always get myself caught up in these situations. I don’t know why I do it, it’s like I don’t think before I act. Anyway, I used to text this guy. I didn’t like him romantically though. Basically we were talking for a few months and he asked me to be his girlfriend and I was like sure, okay.. Even though I didn’t actually wanna be. Now, as I said, I didn’t like him romantically so I honestly don’t know why I decided to say yes. Anyway, we met once in person.. I still didn’t feel a connection.. At all. If anything, I felt uncomfortable. So, I blocked him after that night because I honestly didn’t wanna lead him on. I definitely didn’t wanna lead him on, but I knew that’s what I was doing even though I wasn’t intentionally trying to. So I went back onto the dating app a few months later. I saw his name pop up again.. I was like sh*t… So he messaged me and he basically wanted to start the whole relationship thing again. I did this stupid thing again and said yes. Can someone actually tell me why the f*ck my brain makes silly decisions? It’s like my brain is controlling me. We’ve been texting non stop but I’m just not in the mood to talk to him because I don’t have these feelings for him. I also don’t know how to get myself out of this situation, I put myself in it and it’s just difficult. I don’t want hate for this, I know people are gonna leave nasty comments but I’ve actually tried to get help therapy wise. I called a therapist right after Christmas and I still have not had a phone call back from them.
