Am I wrong

Hey all ❤️ I wanted to get your opinion on something..if you felt something would be beneficial for your mental health and for financial reasons, as well as good for the kids, would you do it even if it meant living separately from your partner temporarily? Our lease is up and the new offer is $300 more than what we pay now and almost every other place is that much too. Aside from the financial aspect, mentally I feel exhausted. I feel like I have 3 kids, not two and I can’t even work right now bc my fiancé doesn’t feel “comfortable “ being home with the kids because he feels like it’ll be too much. He doesn’t help around the house bc “he pays the bills” and it’s just becoming a lot. So my mom said she would love to have us home so I can take time to actually work since she has no problem watching the kids and I can save money versus spending everything I get on bills and expenses. So I really want to go home and do that so I can look at buying a home instead of renting. But that means we would be separated because my mom does not want him living there. He would be able to go home too and save as well, and we literally would be 2 roads away from each other, 7 min tops to get to the others house. I’m completely fine with that but feel bad for the kids for us having to live separately, and of course my fiancé is not helping in the matter of seeing it as a smart move. In the end I think it’s the best option but the guilt of putting that stress of going between to houses on the kids is what’s stopping me. Am I wrong for wanting to go back home and save as well as work on my mental health??
