This is a weird one but I need opinions

Okay sooo I’ve been with my boyfriend for 4 and a half years, we have a baby together and we’re happy.

For the last few months I’ve realised that the way I see men being hot/sexy/attractive I’m also seeing woman that way too.

I’ve mentioned to him a month ago that if me and him were to ever split I’d explore my sexuality a bit more and I’d probably get with a girl.

I’m pretty happy with calling myself bisexual and as far as I’m aware that is my sexuality.

Do you find this disrespectful to my boyfriend if I now open up to my parents, sister and close friends and tell them my sexuality or keep it to myself?

I’m definitely NOT going to leave my partner or explore my sexuality while I’m with him but I kinda feel like I’m keeping a secret from everyone and I need to tell them 😩
