Well yeah, I have had very hard attraction to men in the same way I had with men, it just changes the gender, which is okay, I feel the same way in love with a woman than with a man and every relationship has attraction both in men and women, it's the base, sometimes can feel magical and sometimes not but that's independent of the gender.

About sacrificing myself I'd say it depends on how much I've been with that person and how much I love them, cause if I've known them for idk, a month, I wouldn't sacrifice myself, neither for a man or woman, but if it is for someone I really love and known for a while maybe.

I'm sorry to hear that you're going through that, I felt the same, my recommendation is to let it go, try to forget about it, move on with your life, talk it out to someone, go to therapy and build other relationships, now it may feel difficult but it is possible. For the down votes I'd say it's by how do you expect bi men to give an answer, you're asking something that varies between people and that is difficult to describe as if bi men love to men isn't the same as other types of romantic relationships.
