I need help

Ok so I have a question for those people with a boy/girl friends.Would you rather have a boy/girlfriend or a lot of friends. Once I went out with someone my friends hated, I almost lost all my friends. And it was one of those things that you have to really think about. Thankfully, the person I was dating made the decision for me. Ok so a friend I used to like is moving and I wan't to ask if they are changing there phone number, so we can see each other, but i'm afraid to ask because my friends jump to conclusions a lot and I don't want them still like him. Should I ask? The problem is that tomorrow is the last time i'm going to see him so pleas help!!
