So firstly, some back story on our relationship and financial situation: 

My boyfriend and I have a mortgage together along with the normal bills that come along with owning a home. Plus 2 car payments, student loans, etc. You know, the typical bills everyone is overwhelmed with. My boyfriend makes close to 60k a year where I make closer to 35k. Our mortgage is roughly 1800 a month. We have a daughter together and I have 2 other daughters from a previous relationship. Currently, he refuses to get a joint account. I’ve tried to push combining our finances but he refuses at this point. I believe it’s because he distrusts me with money. So he currently pays for the mortgage, car insurance and his phone bill. I pay for everything else. The electric, water, both car payments, internet, Netflix subscription, daycare costs, our mutually shared credit card (that we used to pay for renovations in our home) and any other expense you can think of incurring. I foolishly wracked up over $6000 on a credit card by buying items for our home such as a new mattress and other household items. I can’t remember the last time I purchased something for myself, alone. Everything I purchase benefits all members of the family or is used by the family. I also have an agreement with my ex that I will claim the kids and give him a percentage that matches the amount time that he has the kids, so about 40% of what I received for the two oldest. 

Now, I did get a decent amount of money back this year. I was really excited at being able to pay my credit card off and having money left over for savings as it just makes me feel secure having it in there. Well, my boyfriend asked for his half of the return for the children since he provides for them also. So after paying off my credit card and giving him his portion. I now have only $300 in my bank account. Am I wrong for being pissed for having give this to him? Every pay period, I am struggling to keep my head above water with all the bills I pay. I’ve tried talking to him about how I understand he thinks it’s “fair” for us to pay 50/50 of the bills. But I think he struggles to comprehend that I also make nearly half of what he does. I’m constantly scraping by every month and never seem to be able save any money. 

Am I the asshole for being disgruntled and pissed off for having to give him half, leaving me with virtually no left over money for my own security?
