Ok, so my mom started a new job about a month ago, and we already know some of the workers there well enough because we shop there often. Anyway, this guy asked her for my contact information, and she gave it to him without asking me first, which bothered me, but still not the end of the world I guess. I don't mind getting to know people, and I added him to Facebook because he's always been friendly towards me. My mom said that he must have had a hard life because he has brain damage, it's not severe or anything, but it still makes me feel sad for him. The main issue is that he sends messages constantly, and if I don't answer right away, he asks if I'm mad at him, if I'm there, if he did something wrong, on a repeated basis. People that know me know that I like my space, and when someone wants to talk to me continuously, it makes me feel closed in and anxious. Besides that, I can't always be around to respond right away because that's not realisitc. My mom said I'm being mean for trying to set boundaries. So I feel guilty and feel like I'm being cruel to someone who is essentially disabled. I was wondering if anyone had any advice on how to handle this in a tactful manner.
