You walk into the video store with your significant other and he/she started flirting with the person behind the counter... right in front of you? I tried to get a word in edgewise and be a part of the happy exchange but I was blocked. After the fact I mentioned it, and he said that he wouldn't normally flirt with someone but thought it was okay since I was there and it made him feel good that someone other than me thought he was interesting. Should I be worried?
