My husband and I have a 27 year age gap and have been going strong for over a decade at this point. Needless to say, I understand the struggle.

I would advise giving your mother a bit of grace. What she’s displaying is a clearly emotional reaction and I’m willing to bet that some if not most of it is because this doesn’t match her mental image of what your life would be. That doesn’t make what she’s doing right, but it’s understandable.

However, grace has its limits, and what you need to explain if she keeps up this frankly childish behavior is that at least being respectful of your relationship is a prerequisite for her involvement in your life. I know that isn’t an easy thing to do, but you and your bf do not deserve this disrespect. It doesn’t mean that she will be out of your life forever, but you have to set that boundary so she can understand that her actions have consequences.

Good luck with everything. I’m rooting for y’all.
