This is probably going to be long...
I need to write my dp a dear Jon letter, it's the only way I can sort this mess out without crumbling.
I have been with dp for 18 years and we have 3 lovely children. Every year dp gets a new hobby that takes up his time leaving me stuck at home.
The latest one is keeping fit. He drops our dc off at school and goes to the gym every weekday.
He spends for hours at the gym, comes home has a nap then picks the dc up again.
This has been going on ever since January. He refuses not to go. We have no days out together, not even with the dc in the holidays.
But if his friends organise something he will go. He even goes on our birthdays 
He goes out to the pub every Thursday and Friday too. I'm never invited. His friends take their girlfriends though and the girlfriends take their friends.
I'll call him and hear them all having a good time, it hurts so much knowing that he doesn't want me there.
He actually said he doesn't want me there because he can't be himself.
He goes for days out with his friends and their wives/girlfriends too.
It's all come to ahead today. I've broke down to him about the situation. I called him lastnight while he was in the pub and heard girls laughing.
Dp doesn't work. He has a business which he pays someone else to run. That's why he has so much free time.
I work, come home, sleep and repeat.
He's always been like this. We have 1 picture together which was taken last year.
We have never been on a proper night out together, we've never even danced together.
I feel like I'm missing out. I just don't know what to do. He refuses to change.
Please help me put my feelings into paper.
Thanks
