Husband doesn't want me

Hi im 46 been married for 25 yrs this year

Husband is 10 yrs older than me

We used to have an amazing sex life and our chemistry was off the charts

However something messed up big time 10 yrs ago and I decided to stay and we were ok sex life was fine again no problems

But last time we had sex over a year ago he lost his errection it happens not a big deal but since then nothing

Cuddles are there but no sex

I know he is older and it could be that ?

But we had a chat the other day and I asked him

What's going on

Is he seeing someone else ??

Does he not find me attractive anymore ??

Or is he having ED issues ??

He answered no to all says he loves me and finds me attractive ect

And said he just doesn't want to that much anymore ( he can get errections as he is always satisfying himself)

he said

Maybe we need to go out together and connect more with each other again

Ect to bring back the spark

However I know there is more to this and do not want to waste another year of my life waiting to see if he wants me

I know he's not being honest about why he doesn't want to And I feel it's now affecting my mental health and I refuse to allow this relationship to do that to me again last time I spiraled really bad and literally it was only my children that made me get through it ( they are all pretty much grown now youngest is 15 )

So anyone have any advice or suggestions please
