Is a 15 year age gap too much??

I’m a 21 year old female college student who is in a quickly developing relationship with a 36 year old woman, and I’m a bit concerned about some things. The age gap is one of them amongst some other things. I’ll begin by explaining how we got to this point.

We met in January at my little cousin’s communion dinner and were seated next to each other. The only reason she was there is because she’s my little cousin’s, grandma’s, sister’s friend who was brought because she was visiting where we live, to get to know the area since she planned to move here. We talked nearly the entire 3 hours we were there and got along really well. We exchanged numbers and stayed in contact for the next 3 months before seeing each other again. She has since told me that during this time period she apparently had a huge crush on me. I honestly did too but because I’ve had crushes on older women since I was 12, so it didn’t phase me. In the past I was always too young to do something about it and even if I did I would’ve gotten shot down since half of them had husbands.

This woman is single and childless, and complains about the pressure of settling down daily. So I would say I’m safe on that front. In the beginning of June she confessed her feelings for me. She said she didn’t tell me sooner because of how young I am but decided to confess when I told her that my only ex girlfriend was 4 years older than me (I was 20 and she was 24, calm down) and I had also told her I’m into older women.

I should say that I have been compared to an old lady and a millennial my entire life, so it’d be understating it that I’m an old soul. I’m an only child and have always been more comfortable around older people than people my age anyways. I’m not the going out or partying type and I never have been, I get really bad anxiety when I do. So I have more in common than most 21 year olds would with a 36 year old is my point. But not as much as I would like.

Here’s where the worry comes in, she’s not your stereotypical middle aged woman. She likes to go out and drink(I’ve seen her drunk over 10 times) she likes to date around but says she’s serious about me. She asked me to be her girlfriend, no hesitations involved since the first time she confessed that she liked me. To be honest I was still put off by the entire thing and still am. We’ve been together for 2 weeks now and she’s wonderful, though she practically lives in my apartment.

I don’t know why but the entire thing weirds me out, though it shouldn’t. She’s very sweet to me, listens to my random rants about my interests and has my schedule in her phone so she knows when to “bother me or not”. There are some orange-ish flags like the fact she’s not bothered by our age gap, she tries to convince me to drink with her more often than not(I’m not drinking until I’m 25 so my brain can develop properly), If I don’t do what she wants she gets weird especially regarding sex and as I mentioned earlier she likes to date around, but says she’s serious about me. My friends say I shouldn’t believe her.

My ultimate question is, should I continue this? If you have any questions about the situation please ask, I’d be happy to answer but I do need some honest advice. Thank you for your time.
