I (28f) met a guy (35m) on social media about 5 days ago. We started chatting. He's nice, he's decent, he has a good job and we have many common interests. But I'm not interested in a relationship with him and I just find that he's too enthusiastic about me. He wants to be texting me all day, every day, always wants selfies (which I don't give to him) and he's talking about wanting to fly out to see me. It's only been 5 days!!! I feel like I'm under surveillance because he's always asking me about what I'm doing at that moment. I'm the type of person who doesn't like to carry my phone around all day, I prefer to put it down and go do my outdoor activities and stuff. I made it explicit that I don't want a relationship, but he still insists on us being friends. This whole thing feels really suffocating, and when I try to tell him that he just says he's sorry and then keeps on. And when I don't text him back he guilt trips me.

So the question is, now that I've definitely let things go too far, how do I lose the guy? He's not a bad dude per say, so I don't want to hurt him. I just want to convince him not to talk to me so much.
