So you majorly messed up with your guy. This may be one of the trickiest sitches to get into, because (gulp) unlike a bestie or family member, this is someone you may well have been intimate with–and he’s someone who can leave. That’s a scary thought, but you need to ask yourself: Are you truly sorry for whatever you did, or are you simply scared of being alone?
If it turns out you really do feel legitimately guilty, the last thing you want to do is bug him. Most guys aren’t born communicators, and a lot of them tend to get quiet when something is bothering them. Don’t force him to respond to you right away, but let him know how you feel: Make eye contact, touch his arm, and let him know how sorry you are that you hurt his feelings. Ask how you guys can make it better and prevent the same issue from coming up in the future. Guys are inherent problem solvers, so he’ll probably be open to coming up with solutions with you when he’s ready.
