<human>: Can you succinctly summarize the text in 1-3 sentences?

This is straight forward. We have been dating for a year and 2 months now. I don't want to get married yet but I always wanted to get married around age 25-28.

We had the talk today and she said she doesn't want to get married until she's close to 30. This sucks for me because I'm 3 years and 10 1/3 months older than her. I want to be settled into marriage and don't want to be in my mid 30's when I have children. 

Does anyone have experience with age difference. Eve though its less than four years difference it seems to make a difference in stages but not so much emotional maturity.

What strategies could make this work?
<bot>: gf is almost 4 years younger and I don't want to wait as long as her to marry and start a family
