So I work with a lot of men and probably have a more open group of friends than my SO. I once commented that one of the men I work with was very good looking but knew he got with a lot of women. Recently he's been messaging me. Just small talk I try not to respond but is awkward if I don't because we work together. My so saw a message and got really upset (it was just the other guy messaging me I hadn't replied). Today the guy messaged me again asking me out on a date and saying what he thought of me and I can't help but feel terrible for replying. It's awkward because if I don't respond it's awkward in work and by responding I could be potentially showing interest even while keeping things short.
