15 year age gap, in older age

Even if, when you are 55 and he is 70, things begin to unravel, you will still have had 25 happy years with him.

Go for it if everything else is good within the relationship. Yes, it is possible that you may have to do a lot for him when he ages but it is not certain.

If you were 55 now and he was 70, I might say "think carefully" because he would be nearing old age right now.

I wish you well.

Of course the internet will be full of horrors and disasters. Happy endings are all rather dull (in that context).

This man is someone you are happy with, you tal about all the things that make marriage work - friendship, a great partner, amazing Dad to your shared child.

I think most of us have a panic about whether we are doing the right thing in the lead up to the wedding. I certainly did and so did most of my friends. It seems such a big step and (theoretically) irrevocable. I actually think that is quite a good thing.

No one knows what may happen tomorrow, let alone next year, the next decade or 50 years hence . I mean - who forsaw COVID and its effects.

Someone has already quoted Joan Collins' famous words on marrying a man 30 years her junior. What more can on say?

Thank you all for your input.

I think your main problem is comparing your settled family life to your single friends party lifestyle.
If you split up from your fiancé you wouldn't be footloose and fancy free like them, you'd be a single parent trying to balance work and childcare. Not a better option.
I'd say fast forward five years or so and these friends could well be worrying about their biological clock running out for them to have a baby.

At 30 you're not too young to be a mum, plus you still have plenty of years to pursue your career as and when you're ready to do so but with solid support behind you. Lucky lady!
You say you feel "at home" with your fiancé. That's where the heart is remember. Enjoy your wedding ?

Carpe diem! Seize the day!
Don't be impetuous, and make mistakes, but ponder and then act.
You sound to be happy, so relish your love for each other.
I have seen folk who are FAR older than their years and are a drag! And others who are young at heart!

Life is for living! Not cultivating Job's comforters.
Go for it

Worrying too much, way too much about him being 75.

Can’t say any more. I have a sudden urge to grab my 76 year old and take him to bed!
