I would recommend that you put "straight" on your must list for selecting a life partner - for your sake, his sake and the sake of the future children.
I am not anti-gay, I am anti deliberately making terrible life choices.
You may not be anti-gay, but you are clearly anti-bisexual and lack common sense and understanding. Please don't presume to know how bisexuals thing, act, or feel when you clearly aren't one and don't know. OP, ignore this person. Confront your partner and ask. He may well be cheating on you, he may not. What came first - who knows. He could be cheating because he wants to be with men now. He could be stepping out because he fell out of love with you first and it happens to be a man. Hell, there could be women too. Or maybe he is just looking at pictures. There is no way to know without asking.
That said, ups and downs in relationships, and cheating, are not some craziness that are exclusive to bisexuals, nor is monogamy exclusive to non-bisexuals. People are human, and humans do things that are good and bad, but there is literally 0 way for you to figure it out without asking.
