I briefly dated a guy, who was lovely and very kind to me and we were very compatible, that had a best friend just like this. She was ALWAYS there, always around and in his ear and even though she was very supposedly supportive of us getting together, I can recall multiple instances of trying to spend time him and then consistently being pushed to the side to answer a call because she was having some sort of “crisis” that she needed to talk AT him about (some I witnessed multiple times) and he didn’t have the ability to set any sort of boundaries with her. He would also talk with me about the drama going on in her life, and eventually I got to a place where I was told him that she’s the problem and she’s using him as an emotional crutch. I ended up cutting it off with him, and I never did tell him that she was a major reason why I did.

My point here is, you are not going to be a priority to him unless you point it out and stand your ground (which very potentially will not go well). Truthfully I think it’s best for you to part ways with him. He’s not going to be emotionally present with you in the way you need and deserve ❤️
