I'm going thru the EXACT same situation bro, my mom, sister ,and one of my younger bro's knows, and have been debating on telling my Dad This week. My mom and sister advised against it when I came out to them and told them I had a BF(first guy I have ever attempted to date). I think he needs to know, we are really close and have a great relationship. I am just scared of telling my Dad because I wouldn't want him to internalize it and think it's something HE did wrong along the way. My parents recently divorced after 27 yrs, and he didn't take it so well emotionally. Plus my Dad is def very old school. I do know that even tho he may have a hard time with it at first being that I am his first born son, and he expects grand kids etc...He would still love me know matter what, he is a deeply compassionate guy.
So, yeah...being bi is hard...people that aren't really don't understand. I myself am leaning more twds men as life pans out...It's just easier, less games, drama, and headache. I was dating a guy who was AWESOME, just like dating my best bud, we see eye to eye, never fight(on a serious level)and enjoying being together every chance we get. If I am going to be with any guy, I found him...If want to be with a woman, I can...but so much is excepted, and I am not one for living up to others expectations. I pave my own way, you should to buddy. As time goes on, this will all seem so trivial. You will figure it out, no need to rush it.
