Being ignored 😢

Me and my best guy friend had a falling out when I got with my current boyfriend. I recently tried reaching out to him and he ignored me. What’s so bad about just being friends with a girl, with no opportunity to bang her? Why is that so bad? Like it’s hard to accept we will just never talk ever again, and he’s ok with that. I would feel the same way if it was a girl instead of a guy. We were so tight like he was my bro ☹️

Can anyone relate?
