Is it normal for my mother-in-law and my husband to send text messages and make phone calls every day after marriage? I have to tell my husband something at home.

This is not normal. Maybe you just got married and your mother-in-law can't let go of her feelings for her son. She feels that her adopted son has lost a little to others. I suggest you don't think too much. As long as your mother-in-law doesn't answer the phone, let them talk. Don't let a little thing affect the relationship between husband and wife. Take a step back and relax! ! !
