So my fiancé doesn't get why I'm so much on the money , well besides the fact that we have a child on the way and we need to get an apartment and she needs stuff, eventually I'm going on maternity leave so it's just his income. I've seen my parents struggle when I was a child and I promised I would try my best to not struggle like they did. I love my parents to death but I don't wanna live paycheck to paycheck and I don't want that for our daughter ... He doesn't get how important it is to me to make sure we have everything ready. I know not everything will go to plan but at least I have a back up plan and just have a game plan for what I think we should do. I'm getting him prepared for everything pretty much being on him . Yes I work a lot but hell we need money!! I've explained to him this before and he keeps saying oh your pregnant don't worry about it. If the doctors didn't put me on bed rest or anything I'm gonna work my ass off without making myself sick.. I just wanna make sure everything will be ok :(
