Wibta if I'm considering leaving my fiance?
I (25F) have been with my fiance (29M) for 3 going into 4 years we met online on a dating app at the beginning of our relationship I was clear with expectations for what I want life to look like he had agreed with all points. Well he lived about 4 hours away from me and I commuted to see him multiple times due to legal reasons he was unable to leave his county without permission so I was putting in the effort to see him and spend time with him we fell hard and fast I moved to be with him away from all my family to somewhere I've never been other than to visit him and about 5 Months into the relationship I ended up pregnant and 9 months later we had our son at the beginning my fiance was working a regular job and so was I he lost his job due to lay offs so we saw it as an opportunity to not pay for child care and he became a stay at home dad and I continued to work well 2 years have gone by we have relocated to be closer to my family I am currently 6 months pregnant with our daughter and financially we are just scraping by I have a lot of stress worrying about financially supporting a toddler and new baby I have had multiple conversations with my fiance about getting a job so that I am less stressed out and we have enough money to support our children everytime he looks at jobs and either has an excuse of why he can't do it or he says he doesn't trust a daycare or someone else to watch our children I'm also the primary person cleaning and cooking at home so on top of working 40+ hours a week I'm also cooking and cleaning at home trying to keep up it's drowning me I'm exhausted and he will do things if I ask him to but he also throws a fit about it the entire time he likes to sit at home and play video games and talking to his family if he doesn't get a job soon I'm considering leaving him I love him but I never signed up for a toddler the size of a grown man ... we have a child and one on the way so would I be the a*hle?
EDIT ADDITION Just for clarification he wasn't like this in the beginning he was super helpful and supportive with literally everything and after our son came to be it's like a light switched off in his head and he forgot how to be an adult ... and it's just declined further and further he takes amazing care of our son he just never cleans up behind what he does do ... he makes food for our son but I always make dinner for the two of us I cannot just stop cleaning the house because he won't do it I will not let my children live in filth what I get done in a day isn't perfectly clean but it's enough that we don't have trash everywhere and dirty dishes laying around our apartment definitely looks lived in with toys and clothes thrown about but toddlers do not leave clothes in dressers and toys in the designated bins so I consider that normal
