In Law Update

My mother in law called last night. She said she called my husband Friday at four o'clock and he didn't sound drunk. I don't know what that means. Does she think I'm lying? She also told me she had dinner with my brother in law. I asked her if he talked about my husband. She said no and I told her about the card and nasty text message he sent. She was shocked. The next day my husband gets a apology text from my brother in law. Did my mother in law have something to do with that or did he do it on his own? I don't know but I think it's time to let this go and focus on more important things in life.
