Calivano, please make sure that the counselor talks to both of you together AND separately. You are both more likely to open up more without the other present at first. I wish you the best of luck making your marriage work. I will mention one thing that might seem a bit cruel, but I want you to be aware of the possibility. Your wife may actually be wanting to end the marriage, but because of her insecurities and emotional issues, she's trying to force you to make the first step. That way, she can always say you were the one who left and thereby justify everything she did. Don't allow yourself to be put in this position. You might consider bringing the possibility up with the counselor. And the only thing you have to "man up" for would be your kids. Especially girls. They need to see an emotionally healthy, stable parent. They need a father who exemplifies what they should want in a husband. Children see and hear everything, they just don't understand it all. Be there when they don't understand.
Qrinta, having been in a retail family for a long time, the thing your parents have to ensure is that Walmart pays them what their selling price is. You parents need to be the ones issuing the invoices, not Walmart. Walmart can issue purchase requests, but not invoices. And I certainly hope your parents don't send out product without first getting payment! I wouldn't trust even Walmart that far.
Also, what Walmart then sells the product for is their own decision. I believe it is against federal law for companies to mandate a set price for retail. That's why it's called a manufacturer's "suggested" retail price. I know this because some of the major cosmetic companies got into huge trouble back in the 70s or 80s because they required retailers to sell their products at a certain price. If every store has to sell an item at the same price, there is no competition and that's not good for the economy or the end consumer.
