Coming out to my mom...?

Si

Hi guys! So rn I have a boyfriend but I’m bi and I have dated other girls too. My mom says she’s fine with gay ppl etc but every once and a while she makes these little jabs or “jokes” that piss me off. I don’t know if I should come out to her or if having a bf rn will be confusing cuz she really doesn’t seem to understand what bi means from what I can get. Any advice?
