I’m been broken up with 3 separate times when I told my partner I was bi (rather than gay/straight) and my family (who I am out to) have all talked about how they could never date a bi person and it really hurts because I wanna be proudly bi I wanna be proud of who I am but it hurts
I’m sorry about this, people can be biphobic and awful.
Remember that your attraction to both men and women doesn’t invalidate your attraction to your current partner. If they can’t see that, then it’s their loss and you deserve way better.
One day you’ll find someone who won’t bat an eye at you coming out to them, and you’ll be happy. It might seem grim now but things will get better.
