My SO just told me he was bisexual and I’m not sure how I feel about that.

We were talking about me being the only person he texts with when he mentions a male friend that liked him and I was like 😨 and i asked him, do you like guys ? And he said, « yeah, I’m bisexual. I meant to tell you but I didn’t know how you’d react. »

Don’t get me wrong, I have an open mind and I have gay and bisexual friends. It just feels different when the person who’s bisexual is your own boyfriend and he tells you he’s been messing around with guys for a while.

Im not sure how to deal with it. I am a pretty possessive person and now I have to worry not only about girls but boys too. And what if he misses being with a guy?

I know my questions are kinda cliché but I’m just confused now.
