Being creeped out by the dorm roommate that only speaks with women he finds attractive.

Who else feels this way?

I shared a dorm with a guy for 7 days and then he came into another room I was in. During those 7 days he seemed to keep to himself. Didn't have any big chats with the other guys in there. Two women showed up and he was still quiet with them.

In the new room it was just me and him. Two attractive ladies show up and he turned to mr. Chatty. He said more words than I've ever heard him say in that brief encounter. He ended up successfully booking up with one of them. They left. He went back into silent mode. Two attractive women showed up again that were the same nationality. He still was Mr. Silent. I find it creepy. It feels very targeted and performative when he socialises.
