Need relationship advice in regards to boundaries?

I have been living with my boyfriend for a year and a half and he was laid off his job and we decided that he could get his Real Estate License. Well of course it has been a struggle and I have been paying all of the bills 100%. I share everything with him. My home/financials/kids/youth/cell phone usage/car...etc. He was a single for 10 years before shacking up. I have some insecurities from leaving a previous relationship due to cheating. I have been a little cautious but then he has also displayed some behavior that has me on alert such as a flirty email to a girl. 2 nights ago, we were just talking and his bank statement was laying on the counter and I pick it up and I said, $12 for Wendys? Who did you buy lunch for? He snatched it out of my hand and started screaming that his bank statement is none of my business, that it is private. I feel it IS my business. We live together, I am paying all bills and I feel that I have a right to see his income and spending habits. Advice Please!Need relationship advice in regards to boundaries?
when someone reacts in anger it is usually a sign of fire behind smoke. yes it is your business. i would be more concerned about his reaction than the $12 dollars itself. if you suspect he bought someone lunch he most likely did and doesn't want you to know who it was. keep your eyes open! make sure you don't enable his behavior by keeping a blind eye to facts you're keenly aware of. The biggest mistake anyone makes is not trusting their instince. Transparency is key in any relationship when that transparency is clouded seeds of doubt begin to sprout.Need relationship advice in regards to boundaries?
Sorry to hear about your situation. Firstly, you do live together but you aren't married, so essentially, he is right. I personally, wouldn't be supporting my children, myself and a grown man who doesn't seem to have any intent or offering my any assistance. In doing this, you are enabling him and to some degree, mothering him. So, he probably feels like he can do whatever he wants you and will simply take it because you have been. My advise, if you are sick of him leeching, let him know it and offer him an ultimatum. You are not a doormat and don't allow him to treat you like one or allow your children to see you treated as one, either.
well.. maybe he took a friend out? and no you dont have a right to see his income and spending habits unless they are way out of control.. like if his kids came to visit and he spent over $2000 on them over a time period of a month on clothes meanwhile he is still paying child support to their mother - then you open your mouth.. not when he spends $12 at a fast food chain - who knows, maybe he was extra hungry that day..
