Last night I discovered my husband had stashed away a fairly large amount of cash in a drawer. He says he has done it by using 'cash back' for relatively small amounts while shopping over an 8 month period to save up for stereo equipment, which is plausible as I also found out recently that he has been looking into this and has even made offers on 2nd hand hifi stuff. He had not discussed this with me and when I found out I pointed out we are trying to save up for a home renovation and don't have any room in our house for it.
However I still feel suspicious as if he hadn't been found out and went ahead and purchased the equipment with the cash, how would he explain where the money for it came from? This makes me wonder if the money might have been intended for something else. Several years ago he saw a prostitute and it almost ended our marriage so I immediately jumped to the idea that he was going to use the money to pay for sex, but he emphatically denies this. I also wonder what else he might have lied to me about that I have never discovered. Also, I would never squirrel away money in secret or plan a major purchase of something that was entirely for my own enjoyment without consulting him, and I never lie to him.
Back story: We are older parents (in our mid 50s) with two really challenging kids aged 11 and 13. We no longer have sex, which I'm now fine with though we did used to have quite a passionate relationship (and as far as I'm aware it was meant to have originally dwindled due to erectile dysfunction, though the fact that he saw a prostitute does put that into question). Generally I feel like we are pretty close and care about each other a lot, and I have always assumed we would grow old together in a comfortable, companionable way. However, with this discovery of the lying and deception I wonder if I'd be happier apart from him as I feel our trust is broken, and he just seems to make really bad decisions sometimes, especially where money is concerned - and despite being in his 50s, he just seems to never have matured very much, and most of his friends right now are single guys in their 30s. He is an ok parent but not very sensitive or proactive, and overly authoritarian. I have friends who notice that our partnership is better than many, and certainly he does stuff around the house like all the laundry and quite a lot of cooking, but overall I am the one who mainly manages the kids, the household (including almost all the cleaning) and our finances, which does lead to some resentment on my part and leaves me exhausted with little time for 'self care'. We both work full time but I make about three times as much money as he does.
I am mainly afraid of the emotional consequences for the kids if we break up (the 13 y.o. in particular suffers from extreme anxiety and cannot handle any kind of insecurity/change), as well as the financial and emotional impact on all of us of having to set up two separate households, plus I'm worried that my life will become even more stressful as I will probably end up having an even heavier childcare / household management workload in the end, and my job is very demanding and stressful. On the other hand, if we separate then he can take the kids for entire weekends and I can have some time to myself! Or maybe I should just adjust my level of trust in him and stick with the current situation until the kids are older ... forget about renovating and just save as much money as possible and then separate and sell the house for two smaller homes in 8-10 years when we are closer to retirement and the kids are more independent. What would you do?
