I know I'm a bit an outlier on this thread but I could have written so many of your posts about the feelings and emotions involved.
I have reread all your posts and now remember why I posted on your thread back in June. I found it so helpful reading all the replies / opinions and could relate them to my own situation at the time.
Advice that doesn't have any skin in the game and detached from the emotions.
I too divorced after a very long marriage (37) years age 59. I truly felt my self esteem, my sense of self and my sexuality were all crushed beyond repair.
A year after I met The One quite randomly and the attraction was off the scale. I'd never experienced anything like it. It was a LDR.
As I said we had different issues (that didn't bother him as I fitted perfectly into how he wanted his life to be much like yours) but, for me after about a year, the issues were really bothering me.
I'd shove the concerns and associated feelings to the back of my mind as every meet up was just fabulous. Like you the physical side was off the scale, great company, no arguing or niggles and so on.
I honestly felt reborn.
After 24 months (thus summer) the love goggles cleared a bit and I saw more clearly the barriers to carrying it forward into the future but they were as they were.
At the point I read your thread I was still in deep but at our age OP, relationships develop with different aims/ ambitions.
It's just not the same as being 20 something and building a whole life together. It's about being together with all his history and current life (his being insecure financially) and yours (still having some years of supporting adult children through education etc)
and the mistake I think I made was seeing it through my 20 something eyes.
The initial lust, fun and togetherness bonding us to then move us forward to build a future life together.
These conversations generally come to a head at around 24-36 months (when the initial fizz fades and grows to something else) and then that's crunch time.
It's also the point when the little annoyances or small differences (that crop up over the months) grow and can be seen a lot more clearly.
That's why I call your partner Mr Right for Now. You've not even hit the first year yet I don't think.
That's why my advice stands (go with the flow for now) as it's too soon to be doing any blending of finances or living together and I feel, as we're older, there's no need to either. Each person is an individual financially and you come together for the top 20% of fizz that the relationship currently provides.
Whilst there's a lot on MN about declining libido around menopause very little is written here about 'Crone Age' (60) and I wouldn't have believed it if I hadn't experienced it myself (and I wouldn't have had the sexual awakening with my XH as he'd destroyed any insatiable desire I had for him physically through his behaviours over the decades).
My body literally worked like a 21 yr olds again. On every level.
I miss him and what we had together terribly and doubt I'll find that emotional and physical compatibility again at my age (62) but I could no longer tolerate the compromises I had to make to sustain it.
And yes, he was devastated and cried and you wrote you don't want to cause someone hurt but you can't bend and compromise yourself to avoid upsetting someone in the future.
I'll get over mine in time as it's still raw but I'm glad the post divorce therapy lessons I learnt really came into play in my situation.
You may get to that point or decide your benefit in the relationship (lovely partner to live life with) is worth the cost (being the main financial supporter of the pair of you which may cause some resentment and affect your children's inheritance etc).
Reframing how you see your future together could be the way forward for now.
He knows he's lacking but he still has 7 years official working life to show you what he can achieve if wants to.
In some ways I wouldn't even discuss it with him, just watch and see. That will tell you more when you come out of the limerant lovely stage in a year or 2's time.
I ll post later in more detail if you like as I have a close friend who was in a similar situation to you and they're now married. And I see the good bits and bad. She has her own 'cost / benefit analysis' on the relationship but I do know she has to crush a lot of 'pissed off ' feelings sometimes. And those feelings do affect desire and can cause disagreements.
