Hey Katie,

I agree with the advice above, about maybe talking to your boyfriend about it. If they have Friday night office drinks, like many places do, or other work things, go along if you can and meet his coworkers, that might reassure you? Just take care of yourself, and be honest with him about what you feel, but be careful that you don't accuse him of anything that you don't have proof of - but tell him how you feel.

It also might help if you start something new of your own like joining a group, or hanging out with friends more, so you both have new stories to share with each other.

Hope it all works out ok
