Yes. Thats like a whole generation gap. I think the older party in that would have to be emotionally retarded to want to hang with someone that young. What would you have in common? I used to work with a guy that was 41 and had a girlfriend that was 21. He got fired because he couldn't keep up with her and in turn couldn't get up in the morning to make it to work on time.
That's a pretty big difference if you are young. I know I would not be pleased about my 18 your old marrying a 36 year old. It's not an equal relationship, like a grown up with a kid. A 40 year old with a 58 year old is a more fair match. Lots more life experience between two ADULTS.
