you said you haven't been in a real relationship in 6 years....you're 25.
ummmmm not to be mean, but......you've pretty much never been in a serious relationship then.
Unless you were in a "serious" relationship in high school...and those don't count.
four kids, then you'd have five, or if you wanted two..6! ack!
No. You're 25! what the heck does he want with a 25 year old, I don't care how mature you are, you should be mature enough to question that.
Like someone said above if you were 43, and he was 58...makes more sense. In your 20's?? No.
eta: my freshman year roommate dated an older guy (like he was 35, she was 19).....No. Run. Run like the wind.
