He should be more considerate, giving everything you have on your plate. Maybe set some boundaries and have him help you more since he isn’t working. If he were to stray it wouldn’t be your fault. You are doing the best that you can. I’m here if you would like to talk.
Talk to your husband about how things can be divided more equitably. Also, if he were ever to cheat, it has nothing to do with how often you had sex. That would be his own choice. Heck, you’d probably have a higher libido if you felt like he was meeting your needs instead of you going without needs met while meeting everyone else’s.
Hey I understand I also have 3 toddlers that want different things at the same time and it can be very overwhelming because there is only one of us try to breath through and pray if you have belief that is what gets me through. I won't talk about my relationship life because I have finished there but we still talk and that's good enough for me .
