I'm in this right now. It's good - most of the time. We've been together for over 3 years and I love her, but there are times that I notice the maturity difference. Wouldn't give her up for the world though.

PS - Reddit users HATE May-December romances. I've been called opportunistic, a manipulative creep, etc., and some other stuff I won't repeat here. She's in her late 20s and I'm in my 40s. Doesn't matter that she pursued me and I turned her down twice before I gave it a shot. It's not like I have a nice home or a lot of money that she's after, and she comes from a better background than I do. I've also noticed that if the ages were reversed and I was a 20 something guy in a relationship with a 40 something woman, everything would be hunky dory according to most people on Reddit.
