I told him he seemed too emotionally attached to her and asked why was he in a relationship, if he couldn't give 100%. like being there in every other way except emotionally for me. (all of his emotional support is going to her). Hed talk about her and I'd be ok with it, he would even tell her about me and us, sometimes a little much more than I'd like.
Either way after we had the conversation he brought it up two weeks later, trying to claim I was jealous. When really I was pointing out an observation considering it involved him brushing my feelings off but expecting me to be there for him, even though he's only open with his friend.
He said he thought about how I felt, then in the second convo he said he stayed up thinking about what I said specifically about him and his friend and that it bothered him. He even admitted to being emotionally attached to her finally, which confirms exactly what I was saying. He said other people have said similar things as me about their friendship but his guy friends don't see anything wrong.
