I'm bi and have fallen for my straight best friend

Well, if she's okay with a lesbian friend, then I'd figure she'd be okay with a bisexual friend. You don't have to tell her you have feelings for her if you don't want to. If your mom is cautioning you not to tell her, I would guess there's a reason. But it may make you feel a bit better to at least let her know you're bi, and gauge her reaction to that. If she takes it well, then you could consider telling her how you feel. If she seems kinda sketchy, then I'd leave out the feelings part.

 

Hello, let me share with u my experiences, im a bi as well, i started to feel that way when i was in high school but ignored it,i also had bf's before until college when i met my ex, she was my classmate, before our relationship started, she was into my friend, that time i was afraid to even try it as i maybe rejected and when i knew she's into same sex relationship,that was the time i asked her,it lasted for only 3yrs,she was my first..and then after that, i had a bf and got enggaged but sadly,it didn't worked out..after 3yrs of being single,i met my present gf right now, it's funny how we ended up together, i've seen her somewhere,she caught my attention but didnt mind at all because i was still in a relationship so i let it pass,then 5yrs later, i met her once again at my aunt's house, her mom was a family friend and didnt had any idea,it was like a destiny, that was the time i get to know her that much and found out she went to an exclusive (all girls) school and had a background of having the same sex relationship but for her,nothing is serious about it, right now we're still on for almost 5yrs now,i am her first and maybe her last..but, unfortunately, she recently got married, it was the most painful i have ever felt, we're still together though, she didn't want to give up on me either but on my part,it's killing me! I maybe stupid because i still chose to stay with our relationship but really it's very hard..

What i am trying to say is that, make sure to know both sides of the situation if it will gonna work or will just end up nothing or end up hurting you at the end just like what i am suffering right now.. And make sure you can handle every move you'll gonna make..
