Help 15 months in.....

I have been married for 15 months now. Since having baby no. 1 things haven't been the same. Not in the bedroom (not just that) but between us. We always argue, I'm 'always, wrong it's never him, I show Lack of emotion towards him etc. I constantly feel I'm doing everything, he fails to realise im a full time mum/part time customer service rep /full time house keeper. Anyone else feeling this way? I haven't laughed in MONTHS, feel sad, feel a lack of support from him as a husband and a father. help?!?!? 😢
