My SO and I had an argument the last time I went to visit him (doing LDR) and I went off to the kitchen to vent my frustration.

I did not know anyone was home and we had the house to ourselves the entire weekend hence I was a bit loud in my frustration and post argument blues. I only learned later that my SO’s housemate was at home the entire argument (including my venting)! He heard everything!

My SO spoke with his housemate, explained to him I didn’t know he was home but the housemate still thinks I’m a crazy and have ADHD.

I’m going down to visit my SO this weekend but I’m too embarrassed to face his housemate who will be home at the time. Should I say something? I can’t guarantee I’m not going to argue with my SO from time to time (and every time it sounds like we’re breaking up, but really we’re fighting about dumb things like where to go for holiday etc). I feel like I’m walking on egg shells around the housemate. Help!
