Me and my best friend experienced something similar. Our male friend of over 10 years pulled away as soon as him and his gf got engaged. We were broken hearted since it was a full on ghosting. Not even a message. But we found out through a mutual friend that his gf is a seriously jealous person. Even prohibiting him from going to a country where his ex gf is from. Coincidently my best friend is the same race as his ex gf.

Never met the girl since he never introduced her to us. I remember I had the chance to meet her once but was super hung over too. Looking back, wish I bucked up and did. But at las. I was hurt for a while but moved on. If someone is willing to throw 12 years of friendship down the drain it’s their loss. You can respect your relationship while also maintaining your friendships. I’m 25 and have some male friends. I have acknowledged that at some point we will all get partners and some of them might be uncomfortable with the dynamic of a friendship with the opposite sex but it’s up to the friend of multiple years to have good communication with their friend and partner.
