Mate Guarding and Other Unacceptable Behavior

I'm at an event last night with my girl. It's a dinner/social event for her firm. It's kind of stuffy, mostly suit and tie, and not all that exciting. We're hanging out, having some drinks and she wanders off to mingle. I know people there. She doesn't have to babysit me. I'd rather her do her thing.

I see a chick who is friends with my girl and the wife of a guy who works at the firm. She and I are also friendly. She's very attractive, maybe like an OT 8 or something stupid. She's standing by the bar waiting on a drink so I walk over and start making small talk. We're people watching, joking around listing random retarded things that are more exciting than the event (watching Ancient Aliens, playing Uno, etc.), I pitch her my theory on fat people and babies needing to be banned from airplanes, yada yada. This continues for a good 10 minutes. She's laughing. We're enjoying ourselves.

Her husband walks over, stands next to us and doesn’t say a word. Just stands there. I thought maybe he wanted to talk to her about something so I slide out to grab another drink. When I walk off, he walks off. I get my drink and notice that she is standing there again by herself looking at her phone. We make eye contact and she mouths a few words that I couldn't understand so I walk over to see what she said. We talk for a minute and make a couple jokes, and then sure enough, her husband walks over from across the room and stands right behind her. Not saying anything just looking at his phone.

Do you realize how sad this behavior is? He wasn't even attempting to hide his feminine behavior by engaging in conversation, he just lurked like a creep. I actually felt kind of bad for dude. If you have to hover around your girl to make sure she doesn't fall on Chad's dick, then it's time to find a new girl. Don't be this guy. Be anyone but this guy.
