Doesn’t sound to me like you’re really that into this guy and that you’re looking for reasons to end things. That aside, you need to decide whether it’s worth getting involved with this guy. You need to sit down with your friends and ask them how they feel about the situation, because if things don’t work out with this guy, it could become awkward for all of you. On top of that, you need to make sure you’re making as much time for your friends as you are for this new guy. It sucks going from being good friends with someone, then getting cast aside as soon as some guy comes into the picture, to finally having to be there for her when things don’t work out with him and she’s lonely. Don’t take your friends for granted. If you’re serious about this guy, then explain that to them, and figure out a way to make things work.
