Okay so my ex and I still hang out sometimes cuz we ended on good terms. But lately her cousin has been hanging out with us and I notice weird things they do. They both share a lot of physical contact,they were horseplaying the other day and getting all over each other wrestling on the ground. They sit next to each other all the time and he would hug her sometimes. Like they're always close to each other and playing,hitting,one time even layed down on the couch together chillin and shit. Stuff that a guy does when he flirts with a chick,she seems to accept it quite well. Now I know her very well and know she's being completely innocent about it and means nothing by it,but what about him. Any thoughts?
