Relationship issue

Okay so I try to make this as clear and short as I can. But I have been in a relationship for about 2 and a half months now and I can honestly say that I don’t think I want to be in one anymore. I feel like the relationship moved so fast and now that I look back at it regret. My boyfriend is really attached emotional and physically to me and I feel like that is why I can’t just break it off after 2 months. We said “I love you” literally less than a month into the relationship. Noted that we have been friends for about 2 years. I feel like I have live for him but I am not in love with him. I was never physically attracted to him till recently and we have been intimate since we began to date. However, almost a month in I haven’t been able to get intimate with him (not even a kiss), and I am no longer sexually attracted to him. I feel really bad and I don’t want to hurt his feelings because I am shitty for that. But it’s hard when all my friends and my family keep saying things like “we are perfect for each other” and blah blah blah. It makes things worse when I know that I don’t see a future with him, and I know he does. I really need some honest advice because I’m not sure how to go about this.
