Maybe it will help to write it down.
Been together 11 years. One DC who is 1.5.
We have always been independent people but since DS I in particular have really struggled with the lack of freedom. I am a selfish person if I'm honest and felt trapped lots of the time. I absolutely love my DC and as a SAHM most of the week and do everything I possibly can for my child however need an hour a day to be 'me' in order to stay sane, DH begrudges me this and complains every time I go out.
He calls me selfish and says I am a bad mother for going for a walk with the dog or riding my horse for an hour once he comes in from work. Maybe he is right I don't know.
He has lots of time before I go and also when I return but he goes to bed at 8pm out of choice so does nothing. Given the choice he will stay at home and watch TV and never goes anywhere.
I now feel guilty every time I leave without my son, even though he is out of the house so much. He works away lots and I hold the fort all of the time in that respect but if I go out he hates it and creates a terrible atmosphere.
DH does nothing at all. He is lazy, given the chance all he wants to do is sleep or laze about which I hate with a passion. I look at him and it annoys me that he is doing nothing productive. He never suggests days out or going anywhere. That I can live with but he criticises everything that I want to do and moans constantly even though I invite him along. I love being outside, keeping fit, riding, walking...everything he thinks is 'pointless'
He has no interests at all, nothing to do or talk about. When he does talk it's moaning about work, the dog, money etc etc etc
I work 2 night shifts per week and he does nothing to help on these days despite me being up for 16 hours straight both nights and having our son during the day.
He asked me to give up my hobbies, to stop going out when he gets in from work for the hour and to stay in at weekends but I really don't want to do this- I feel he is asking me to give up everything I love to do 
He does nothing around the house. He hates our pets and complains about them constantly which annoys me as short of getting them put down there isn't much I can do about it. He wanted them jointly as much as I did however I walk, feed and interact with them and he refuses to even take them to the end of the street to the toilet if I'm busy.
We don't talk really except to argue. I have 0 sex drive and no interest in that side which annoys him. I just feel like he never speaks to me and isn't nice to me so why would I want to sleep with him. I do find him attractive but mainly when he's made an effort, not when he's slobbing about which is most of the time. I'm also knackered most of the time. He said he never tries because he's given up with me as I always turn him down.
Basically, I can't be bothered to sort it out. I have no energy for this any more. We are both treading water and I think he hates me. He certainly doesn't like me that's for sure. He never texts, asks how I am, makes conversation. Nothing.
I watch my friends having fun and happy relationships and it makes me sad, however I could do a lot worse. We are financially comfortable, have a lovely home and family and we are great friends most of the time. He is a kind and considerate man and has never raised his voice to me or our child once. If I left I would be uprooting my DC for my own selfish reasons, he is a fantastic dad and my son would miss out on so much. I also don't think I can cope with DC on my own, I wouldn't be able to manage without the breathing space he provides however I'm not sure this is reason enough to stay. I also am terrified of being alone forever
There's no salvaging this is there?
