How Can I Get My Parents To Accept A Wide Age Gap In Dating?

I introduced my gf to my parents, who met my gf by accident because of a situation where I had to meet them to drop something off while I was with her, and they met her and because of the age difference, they had to give a very shall we say... 'Guess Who's Coming To Dinner' parent reaction to it. I'm 37 and she's 21.

What's the best way to get your parents to accept the age gap though? I mean should I tell them that not everything about an SO is going to be perfect and a gf is always going to have some flaw, just like how my parents wouldn't see each other as absolutely perfect in every way? Or is that not the best approach?

But I feel there is something obvious here that my parents are not considering... I am autistic and I do not have the same maturity level for a 37 year old compared to other people my age.

I feel that I have the same maturity level as her after we went on a few dates, which is why I think it's been going really well. So that is the reason why we seemed to have clicked is because my maturity level is psychologically lower, because of my condition.

But my parents want me to date someone my own age, even if it means the woman's maturity level will be much higher than mine therefore, because of my condition. If that makes sense?

Well, you're breaking the half your age plus seven rule, but I kinda think it's your (and her's) life and not your parents'. If they press the matter, you're a grownup- I think it's reasonable to explain that y'all get on pretty good and you're not happy and the age difference doesn't mean much, and leave it at that.
