The only thing... the age difference is diminished over time. Your age difference is 12 years. My ex 2nd H was 12 years older than me and I can tell you that it is nothing, BUT we started off with me being 26. The difference between 26 and 38 is smaller than that between 18 and 30, and the difference between 38 and 50 is yet smaller.

Still, you will be OK.
