So, I met this guy on the train a few weeks ago, and we started talking and I gave him my number. I wanted to challenge myself because of my social anxiety, but now I regret it. I have turned him down a few times already, but now he sent me a new message and I can't keep turning him down. I do want to meet him, but my anxiety gets so bad that I just can't go out and talk with him. The thing is there is no way for me to avoid him either because we live at the same place, and he sometimes comes to the store that i'm working part time at. Thankfully that's rarely, but i'm going to see him sooner or later. Therefor I don't know how to turn him down without being rude. I wan't to tell him the truth that I don't dare to meet him because I have social anxiety, but I'm so afraid that he won't believe me, or that he's going to think that i'm weird and that there's something wrong with me. I guess i'm just scared of being humiliated. So what should I do?
