So yesterday my fiance and I were at our friends house and our friend has a sister. My fiance and I have only been around her together once but the last time we were around her he was just acting stupid and flirting with other girls in front of me while I was pregnant. Yesterday when she got to our friends he was trying to moon her. I get it that there was no sexual intent behind it but I had to ask him to stop 3 times and he knows I'm uncomfortable around her because of the way he acts around her. I'm sure he wouldn't like it if I flashed my boobs to dudes even as a joke. Idk maybe I'm just being insecure. We didn't really fight about it im just feeling down now.
