My husband of five years has been constantly spending our money on his sister. They go out usually once a week, I am fine with spending time with her but its just every time he goes out with her her spends outrageous amounts of money on the two of them. We both work and try to make ends meet. His sister is four years older then us, works and has her own place. The problem is she always says she's broke. I find out later she spent her paycheck on a new watch or material goods. Its frustrating because lately he's been lying to me and saying she has been paying when in fact she hasn't. I pay our bills so I see our visa charges. I ask him and he lies and says she gives him cash. Lately we've been trying to fix up our house but he gets on my case and tells me we can't afford to go out to dinner we need to keep saving. How can we keep saying when he spends money on her and then tells me we can't do anything this weekend. I am so annoyed and don't know what to do. I try to talk to him about it but he brushes it off. Just this weekend he spent over $300 dollars on the two of them, they went to a wine show and then lunch and dinner. I'm so frustrated and upset. Any advice would be greatly appreciated. I know I can't win against family but I feel like I suffer while she takes advantage of him.
