He's too old for me.

I'm, 29 and some 45-year-old year old is trying to romance me but I see it as manipulation. He says he wishes to marry me yet, he barely knows me and then he said he just wrote me that to "make me happy" when I pointed out that it was way too soon to be talking about marriage. He's 17 years older than me he's so old for me. I was telling my mom that today she's like why would you want to get with some old dude go get with a young man your own age. He probably uses viagra lol. I don't want this old dude but his tactics are a red flag coming on to me too strong is a red flag. I usually date men who are 10 years+ older than me maybe that's why I've gotten hurt before I do like young men but idk, sometimes the older ones are more interesting but yeah, I'd never date a guy that old for me.
