For context this girl he met for two weeks when she was travelling and she also has an only fans so I think they have also hooked up. If they did , then I’m not sure why he likes her posts but not mine. Me and the other girl are both long distance with him but he’s making plans to see me again. He doesn’t comment under her posts but the fact all her posts are sexual is concerning because if they didn’t hook up or they’re just friends why are you liking them. I’ll bring this up when exclusive.
