I'd proceed with caution though.
You're 25, she's 19. It's not that its creepy but, soon yall will be in different stages in life. You'll be ready to slow down, and she'll still be trying to be young, which she is. She'll see you approaching 30, see she's still early 20s and throw your azz down the river

But it can work though.....it really depends where you live. If you in a major city like New York, LA, Atlanta, Miami, Chicago....don't do it

Save yourself the grief. Because what I said will happen. But if you live in a smaller city like Nowheresville, Virginia the relationship has a better chance of working because small town girls get married and have children before 22
