A lot of us feel your pain! trust me. Although I have no children I know whats its like to be broke as hell and everything else seems to fall apart all at the same time. Since I don’t have the extra money currently I have to do the poor mans treatment. Buying Garlic, lemons, limes, etc. These anti-fungals are extremely cheap.
I split everything money wise right down the middle with my girl friend and we have different incomes. you may want to really look at how everything is paid and it should be fair for the both of you.
It’s unfortunate we must go through times like this but anything that’s worth doing isn’t easy.
You will get past the rough moments and eventually succeed. I believe you will.
