He was shy at first towards her, but now he changed and started doing tons of teasing towards her to make her laugh and make her react.

He’s constantly eating her with his eyes and trying to make eye contact with her while laughing anf stuff like that.

He even admitted to her he was trying to make her laugh, all of this with me in the room.

How should I handle this? I get it he’s not seen a piece of ass for years so he needs to act up, but the fact he’s acting like this towards her bothers me. He’s literally filling his lack of contact with women with her.

After two days of similar jokes, the idea that they can’t stand each other in a jocking way has settled. I’m not stupid, I know what men try to accomplish by doing this...

edit: had another lunch with family and he startef again calling her slim and fat just to get her laughing and she is. Mind you guys, I’m not jealous nor scared of him taking her, it’s the fact he’s acting like this that bothers me, his actions and lack of respect.

Sure I could talk to him and come off butthurt, cause you know, a brother joking your girlfriend immediately demands attention. It’s not easy..
