We’re not the same anymore

Ever since I saw that he had nudes of women that I know our relationship has not been the same. I felt a big turn off when I saw those pics. To top it off I caught him jerking off to the pics too. He blames it on the fact that I’m always tired (we have a toddler and 2 dogs) I don’t dress the same (I’m now a SAHM, used to work but can’t afford daycare). I’ve explained multiple times that it is tiring and that at the end of the day I just want peace and quiet. We now have sex maybe once a month but I did notice that he chooses to work more (he has own business and can choose when to work), we have no physical contact whatsoever, barely spends time with our kid, it’s basically he gets home, dinner, plays video games when I bathe our kid and then he sleeps. I’ve told him to make time for us but always says “money comes first”. Also told him that he’s absent minded around us but it just turns into an argument. Next year we will be 10 years together and honestly I have no desire to do anything. I feel that the spark is gone. We are not the same anymore.
