I did date someone of that exact difference. I thought we really connected and I thought we had an understanding.
We had things in common but a lot out of common.
At that time it didn't seem to matter.
As our ability to work as a couple seemed to over power the mishaps...
But then I got taste of his other side.
I would say this, in intimate relationships there is always a moment when one or sometimes even both have a moment where they're falling or feel like they're falling in love and they're hit with a sudden rush of vulnerability/insecurity.
Anyways in this particular moment is when you see some of the worst or the best traits a person has.
In my case this guy started insulting me and tearing down my character.
I went out for a meal for my friend's birthday, I thought I was just going to be among friends some new some old, but it seemed to be double dates, my friend never expressed it but clearly didn't like my choice in partner so invited her boyfriends, single friend.
Upon realising what was going on he after we were conveniently left together.
We chatted and it was clear neither of us were attracted to each other, nothing happened.
Anyways when I came home I told my partner what had happened and he blew his lid. Instead of hearing the innocence, he started to insult me and call me a wh*re.
I could have left when my friend and the others ditched us under the guise of them arguing. My problem is they played on us being nice people, we were both uncomfortable in that casino and looked for a spot to wait for them to 'resolve' things.
I put my partner in his place and he apologised from then on he was under my watchful eye...
Long story short he was protecting his interest whilst he hadn't handled his business.
He was attached to someone else, although they weren't fully a couple (which she confirmed when we spoke) he didn't take the step to end it once and for all.
That's an extreme situation but what I'm saying is sometimes it's not actually about the age its actually about the person and they will always reveal who they are.
The issue with older men is they come with baggage and they are better at tailoring themselves to situations.
I would always say find someone your own age firsts are more exciting and an amazing way of sharing and bonding with your partner.
I'm not saying you can't have that with someone older, you just have to know what works for you, there are genuine and snakes in every gender and age group.
