I over think everything :/

I need some advice on what to do. There's this guy that I have know for about a year but we had never talked before. Last a couple of weeks ago the day after my brothers wedding he was talking with my mom and i was their to be we didn't really talk. Last Sunday I saw him again and he told me he was looking for me on Facebook because he wanted to add me. I told him my name on Facebook. Then he told me something but I didn't hear him I just heard him tell me that his name on FB was ______ and I just said oh ok. But a week has passed and he hasn't added me yet. I don't know if he told me to add him but I feel kinda weird adding him. He used to like my cousin and I don't want to add him really because I know my family and they are going to start saying that I just added him because I want to talk to him just because he liked my cousin. They neer went out but still everyone in my family thinks that my cousin is better looking and everything. i kinda wanted to wait for him to add me so that if they said anything i could just say that i accepted him it was no big deal idont know what to do. I know i could just ad him and get it over wit but i think i kinda like him so its kind of important that i do the right thing. Should I just wait to see what he tells me next time I see him? I know that once I add him or he adds me and it pops up on Facebook they are all gonna be saying that it's weird that I added him if we don't talk really they think I'm really stuck up an full of myself .
