I'm in my early forties and I've always been a loner and never really made friends. Until recently I didn't even know what was so great about them. I don't have any problems socializing, it's just I don't "need" it. I enjoy company but I'm not looking for it. I met someone I really (and surprisingly) like and over the months I started to open up and reciprocate his friendship (I have a lot of acquaintances but I always kept my distance, some even say I was putting up walls between me and them). It was the first time I ever invited someone at my home and the first time I accepted invitations from someone who was not from my family.
It's great. Really. It feels like I now have a better understanding of what being "normal" is and I enjoy every time I speak to or meet with him. On the other hand, I'm now afraid to make mistakes, to be too demanding (I'm not, but since I don't have any experience in friendships, I'd rather choose to avoid contact than contacting that person too much, I don't use his phone number, his messaging accounts, only his email) or to have him cope with teaching me how to behave in social situations. I read as much as I could about friendships on this very StackExchange and on the Internet. I'm pretty sure I can't replace experience with "theoretical knowledge". I'm missing about 30 years of experience and it's hard for me to read people in a non technical/professional situation. I'm bound to fail and I think it's better I stop trying right now.
How can I stop this relationship without hurting his feelings and eventually explain that I'm lacking experience in friendships to handle this situation properly?
