Re: Should my fiance come out as bisexual to my family? Or? What?
Honey, this is a rough one.
I can see both sides. Your sex life with your mate is private, in general I would always advise to keep it that way.
In your situation though, your family already all surmise he is gay, because that is the way he acts. He does not act like a heterosexual man, because he isn't one. At this point, why not just be honest with your family, like he expresses he wants to? It's not like they will be shocked. Why are you worried so much about their reaction to this, since they already feel that way?
If your family are good people, the honesty with them may give you additional food for thought about your situation. They LOVE you, like no one else in the world does, so hear what they have to say. You don't have to agree, or change your course, but listen.
You are both very young. I have many concerns that he will eventually want to explore more with men later on, after years of life and reality set in. BUT if he is a completely managmous person, then he should ultimately remain faithful. I'm trying to think of it from my own life. My sex life is not ideal, but nothing would ever make me cheat, even if a thousand hot men were begging me to bone. Nothing could turn my head from my husband. That is because I am a faithful, monogamous person to my core.
The thing that is nagging me about your baby daddy is that he did have an affair which resulted in breaking up a marriage, and shows a tendancy to not be overly concerned with complete faithfulness. I know he was younger, but he still knew it was wrong, and chose to do it for years. The amount of faith you can put into his declarions of faithfulness has to be somewhat weakened by his past choices. I totally get that you forgive him, and don't hold it against him, but it still happened,
Whatever happens, you are now bound forever by a child. Being young, and in a non traditional relationship are both things that are challenges you now have to deal with. All relationships have challenges, and these are yours. I truly hope that yours is a success.
