Backstory:
In a 5 year relationship with DP which has been challenging at times but on the whole good.
We have 2 beautiful boys - 3.4 & 17 months. I am a SAHM whilst DP is selfemployed working on average 7-9 hours a day 5-6 days a week (this can change depending on what job is needed!)
DP has several hobbies.
He plays guitar in a band, plays for the local football team (on & off), trains at the gym for boxing (just competed in a charity boxing match that was very time consuming in regards to training) and sees friends at the pub regularly. He is also currently planning his own big birthday bash that bwill involve his band playing the duration.
All of this i support (well not so much the drinking at the pub 
but, this has dramatically decreased although he does drink to excess when 'let out') He was a very big binge drinker when i met him (i drink very occasionally and never get drunk!)
We do occasionally socialise together (this has been more frequent recently!)
I am very happy with my role as a stay at home mum but, feel like i have lost my identity. I very rarely socialise without the children (see my friends often but, 90% of the time at play dates with the kids)
I really want to pursue a hobby but, feel totally unsupported by my partner.
I attempted to join the gym a few months ago, bought the gym wear, made sure kids were bathed and fed for him to put them to bed but, the film he was watching at the cinema run late and i missed the class.
This evening i was very excited about joining my local slimming world but, DP had decided to work late. I need to go shopping Thursday evening for a very important piece of my bridesmaid outfit and he has said he will 'do his best!' Which i know to mean 'not make very much effort at all'.
He is a good man who works hard to provide for us.
I appericiate that beyond belief but, does being a stay at home mum mean i have to be shackled to the children at all times?? 
I feel like my desires to be an individual are not important to him. I want a few hours to be without the children but, am constantly being made to feel indebted because 'he works so hard'
So Mumsnet.. Am i being unreasonable?
