Having doubts as to whether it's a smart investment in my time
I would not expect a 21 year old o stay with you forever, she would likely want to party or at least try new guys.
Slippery slope this one. Out of my experience I would say not a good idea. I was the same age when I started a relationship with a man in his late thirties. We grew up apart because I was still young and developing my personality. Between the age of 20 and 25 you change A LOT!
If you just want to have a good time and just enjoy the moment without thinking of building a future with her than.. yeah why not?
Ehhhh it could turn into a long term thing but I wouldn't really count on it.
If you live her and she loves you and you think she's right for you then follow through
If you're doubting it, doesn't that tell you something?
Maturity levels are way different.
21 is grown up, so yeah it's fine.
This is a very difficult question that all revolves what you're looking for at this point in your life, as well as what she wants, and how your personalities mesh etc. In general, the age thing doesn't matter as much as the personality issues. I mean most 21 year olds are boring to most 36 year olds, but obviously that depends on the people. What time are you going to waste if I may ask? I mean, if you're looking for a wife then maybe you are wasting time. If you're just enjoying your life, then you're not.
If she's mature, why not? If she's still "finding herself" I would be careful about taking it too seriously.
Sure go for it however I have heard older men get irritated with younger girls
Enjoy the fun while it lasts.
Sooner or later, you'll probably find that you want completely different things, and have very different expectations.
And she'll probably need another 10-15 years or so of whoring around, before she's ready to commit to anything serious... and by that time you'll be in your 50's.
Get attached to this girl, and she WILL break your heart.
