Am I being unreasonable being uncomfortable with the age gap of my Daughter's relationship?

My DH is 11 years younger we have a 25 yo daughter

Your daughter's relationship(s) are none of your business, OP. So you don't "do" anything. Just leave them be.

it will be a hard life for her with a doctor as a partner, particularly if she is in a rush for children

I'd privately worry about the baby issue too.

Don't say anything. If she asks for advice or vocalises worries you can chat then. Otherwise keep your thoughts to yourself.

Meant to add they've only been together 6 months, he might like the older woman aspect, she might prefer the toy boy thing for a change. They might stay together long term but might not.

Ten years is around max for me personally due to stages in life. He is on a very specific career path and not some youngster trying to decide what to do though so I say embrace it.

My only concern is children as he is young. It’s nice if people can have a life before children. So at least a couple of years dating. She will be 37 and it would be good to start then as much as the anecdotes will start on how someone’s Aunt had a baby at 48 stats it’s more of a risk. He may be ready at 27, my DS sadly just broken up with long term GF definitely wants children and was hoping to have them around that age.

You have now vented and expressed your views on MN, now step back and leave well alone.
If it goes toes up you can then think to yourself 'I knew this would happen' but keep it to yourself. Dd's choice and decision def. not yours.

Take a deep breath.

Now imagine that your daughter is Madonna (66) and her current Jamaican boyfriend, Akeem (28) are coming to spend Christmas with you. What would you say to them?

I was 20 when I met my husband, he was 36. I had my first child at 23 and my second at 26. 21 years later we are still here with 2 lovely teenagers.
Not everyone under the age of 30 is incapable of adulting, in fact the chronic babying of this generation blows my mind.
I am sure a Doctor knows a bit about reproduction and will be aware time is not on your daughter's side, with this information I am very sure they can have a grown up conversation about when/if they want children.
Leave them to it, they are both adults and definitely don't need your ill feelings about their relationship.

I'm guessing you're concerned, OP, that they're not at the same 'life stages' and therefore it won't last and your daughter might get hurt

Or it will last, they'll have children and then he will want to spread his wings and have some life experiences which he's missed and your daughter might get hurt

I can understand the above

Perfectly understandable to worry about things like this

One of my friends is 15 years older than her husband. Theirs is one of the happiest marriages I know, they’re sublimely happy. Butt out, she’s plenty old enough to know what she’s doing, so is he come to that.

I'm 54 and my DP is 42. No issue for us at all and no-one seems to notice the age gap either

I have a 19 year gap and been married 19 years. No, there is no power imbalance, despite MN assuming all age gap relationships do.

I'm 62 and DH is 52. We were 35 and 25 when we met, it's worked for us!

It’s not a very big gap. I would not worry about it.

Are you able to pin point your achual concerns ?
do they both want kids?? That would be my only slight reservation if I was you
there isn’t a power imbalance ???

Age is just a number. They're both adults. It may or may not work out. You say you wouldn't be happy if the ages were reversed. Sounds like you have a very fixed idea of what is "right ".
When we met, my partner was 28, I was 8 years older. I had 2 kids under 10, and although going through a divorce, I was still legally married.
My MIL welcomed me and, 20 years later, she's my best friend.
My relationship with my partner is beautiful.

My kids are happy and grown up and have great relationships with my partner, and my MIL.

It can all work out. Just leave them to it and see what happens. This might be amazing.

I think you sound quite shallow. You can’t judge someone’s character by their profession. I can only assume you don’t know a lot of doctors socially! They are certainly not all pillars of society! Like any profession there are saints and sinners.

your daughter is living her life - this guy could turn out to be the best thing to ever happen to her - or he could be an absolutes selfish asshole. Only time will tell.

Why?
25 is pretty mature enough that there wouldn't be a power imbalance in the relationship.
They presumably have spoken about having children. He might be content to settle down and not to have the "life experiences". He'll be in his 40s when the Kids are grown up so plenty time to experience things than.

The concern is that he won’t want to settle down yet and she will miss out on the opportunity to have children. Then again you could say the same of any man .
Just let them get on with it and enjoy their lives.

I am with you op. I would also find it discomfiting, in my experience a 25 year old is a very different level of maturity to a 35 year old. And males mature slower than women often. And they are at very different life stages.

however, you need to keep your counsel. Be welcoming. It’s a very very foolish person who say anything in this situation. Let them work it out for themselves.

I’d be more worried that he’s a doctor especially if she wants children soon.

DH and I met when he was 35, me 21!

I do think now what if that were one of our dses but at the time it felt right and it still does nearly 30 years later.

You need to stay out of it and be happy your dad is happy.

They are grown adults . Leave them to it .
