<human>: We've been dating since October 2014. I'm 32, he's 49. He used to be a chef and can cook anything and everything. He treats me really well! He's divorced and has 10-year-old fraternal twins, who he sees every other weekend. I haven't met them yet, which is fine with me. He makes me really happy!

In late January/early February I told my mom about him, and while I knew she would have to get used to the age gap, I didn't expect her to get as disgusted and mean about it as she has gotten. She hasn't even met him yet, and a couple of times she has made remarks about/asked me if I'm sleeping with him, has said it's not normal, has insinuated that I'm going after him for his money, and, whenever I bring him up, always refers to him as "what's-his-name" even though she knows what his name is.

I don't know if the way she feels has anything to do with the fact that my father had an on-again, off-again affair with a girl younger than both my brother and me not too long ago (she's been divorced from him for about two years now) or what her deal is.

Give me a shortened version of the text
<bot>: My mother thinks my new BF is too old for me, and so is mean to me about it. Is she overreacting?
