Why does the husband become so selfish after marriage? When he went to the supermarket to buy things, he said he had a stomachache. I always pay the bill when he goes out.

If your husband gives you a large part of his salary, the money in his wallet is very limited to him. He must save some money to maintain his next salary. If he goes to the supermarket to pay the bill, his pocket money will be greatly reduced. If your husband keeps most of his salary for himself, it is very selfish of him not to pay the bill.
