Hi there OP,
There was 32 years between my parents. I'm not going to share much about it, because the last time I did, on a similar thread, some people in here were incredibly unkind about the whole thing. My dad passed away 7 years ago, I loved him to bits and miss him dreadfully, so I'm not going there again.
I think when you just post about an "age gap" relationship it misses the point by a mile. A relationship is between two people, not two ages. People at any age are a complex mix of experiences, personality traits, issues, strengths. It's whether those things fit that counts, really.
It's not always easy, being with someone significantly older. Other people can be incredibly unkind, both behind your backs and to your faces. Others will make all sorts of assumptions about each of you and your motivations. In the latter years, my dad was quite unwell, and it was very hard. When he passed away, even though it wasn't a shock, it was devastating. Mum and I miss him terribly. Every day.
But.
Would mum change a thing? I know for a fact she wouldn't. My Dad was the best of men. She was lucky to have him for the 36 years they had together. I could never have wished for a more brilliant dad.
Her parents, my grandparents were several years his junior. Amazingly, despite not being known as particularly gracious in other respects, they clearly saw him for the man he was, saw their daughter was happy and were unswervingly supportive. She was 22 when they met, he 54. I think this was pretty amazing of them, actually.
I hope I'll be equally open minded if either of my daughters brings home a boyfriend somewhat different from the norm, in whatever way that may be.
HTH.
