I met my guy best friend through this guy I use to have a thing with. My guy bestie also told me he likes me but i dont like him like that. My guy bestie told me about his ex because she works at my job. He told me I should talk to her and ask about him. I did that and we got closer. I made sure to ask my guy bestie a couple of times if its okay I talk to her and be her friend, he said yes go for it i dont care. But now i can tell he is jealous i became close friends with her. Sometimes he calls me when im with her so he can talk to her. Why is he jealous when he said its okay i can talk to her? he's still friends with the guy i had a thing with and i dont mind.
