Do us gays get easily attached or is it just me?

So I have this problem of getting easily attached to people. Ever since before I accepted who I am and came out to my friends I feel like I must always be attached to someone. It basically turned into something I can't live with, I feel pointless without attachment. Everytime I get attached, I know that in the end I'll just get hurt since they obviously must be straight, but I just can't seem to shake it off. I always need to have someone to feel obsessive or protective over. I just want to know if this is just a phase or is it normal.
