Should I confront or not?

[peaceSJ]

During the first couple years of marriage, we didn't have much sex because of me. I was kind of low driver. After having kids, we were better. Actually my H was kind at that time and he understood me. But now he said he was not happy at all and he was took for granted all the time. Besides that, the only issue we have is sometimes he wanted to buy some expensive items but I disagreed due to finance concern.
I explained the reasons to him but he still feels I don't care about him... I don't know anything I can do now...
