I want to let my SO just how upset i am over him not communicating or working together when it come to our money. He gets paid and doesn’t even consult me about anything just do whatever and 7 days later he BROKE, my check is half of what his is and after I pay my car insurance and get groceries and the water and wifi I always have less than $100 left ..the only thing he pay is car insurance, lights and phone bill and he has 4 kids that may need a $100 here and there from him but that’s it.. I don’t even feel secure financially with him at all and I want us to have a serious convo about (even tho we have had plenty) but I want him to understand me and for it not to turn into an argument .I’m at my breaking point .. any advice on how to start the conversation??
