16 with a 28 yr old man

Mrs H • TTC for 2 1/2years
So I'm having trouble in every support group finding girls my age (28) who have a much older husband who has been with him since the age of 16 
I was 16 and he was 28 when we first got together 
That was almost 13 years ago but as long as we have been together we stil l have differences due to our age so I need someone in the same circumstance to relate to in order not to go crazy 
BTW he is 40 now OMG and I'm only 28 and feel 20 whaaaaaat?
