So guess what. My SO and I are left with a $2,500 bill that his mother put in his name and never paid. He is so hurt not because we have to pay it but because she lied to him. She is seriously a manipulative woman and I don't enjoy spending time with her. She does passive aggressive things to me that he just doesn't see. She asked what brand of diapers we would be using, so I told her Honest and she acted like I was nuts. I explained I had an allergy to Huggies and we didn't want to go through that with the baby. What does she do? Buy Huggies for the baby as a gift. 🙄🙄
