constantly fighting

Erin
First of all...I love my husband and just need to vent. No judgement please.
Does anyone else feel like they are constantly fighting/bickering with their SO? My husband constantly bitches about dumb stuff (leaving a light on, cup on the counter, general useless unimportant crap) and I have absolutely had it! Our son is 8 weeks old and my husband works long hours so I'm with the baby pretty much from the time he wakes up to when he goes to bed by myself. I barely have time to shower let alone clean the house but I still try to do what I can in between feedings and trying to pump and enjoying my little boy. Every time he bitches at me, I get really upset. He has no idea how hard it is for me during the day and everything I do for our baby. I am so sick of all the snide comments he has been making. I am doing my best but it would not kill him to do some stuff around the house or with the baby as well. I get so frustrated and upset that I end up yelling at him and bringing up all the stuff he does that frustrates me....gets us no where. It has been hard for me to not lose my mind on him. I'm going shopping now just to get out of the house and get a little space bc I don't even want to look at my husband right now. 
Anyone else feeling like this?
