She'll do to you what she's doing to him, so abandon any romantic ideas right now. Secondly, I've dated 18 year olds while in my 30's. They basically aren't worth it. They dont know anything about a relationship, they dont know how to cook, they want a "daddy", which means you have to do everything for both of you just like taking care of an actual child. She's not going to be bringing much money in (if at all), so your mortgage/rent is all on you. The parents are probably going to disagree (though I have met some parents that were actually pretty cool and wanted their daughter to date an older guy who will take care of them and has a stable life. No 18 year old male has a stable life, they just wanna party and fuck).
The most annoying thing about dating young is having to teach them how to actually be in a relationship. How to communicate. Most people dont know how to do that, especially younger WOMEN. If you just want to fuck, go ahead, but thats not healthy for you on a personal development level, and 18 year olds really aren't that much different from a 25 year old. Thats kind of a myth spread around by horny incels that cant actually get laid. Get ready for her to just lay there as you do all the work.
