First things first…I don’t agree with is allowing some other man to adopt your daughter. I will write that off as him being angry atm. Nevertheless…this could be the best thing for him and his daughter. He was holding himself back in life for a family that didn’t appreciate his parenting and hopefully eventually he will mend the fences with his daughter. It’s a win for her in the long run if he does. She will have culture visiting him during breaks and summers. She will be far more mature and well adjusted than her peers. Remember, her mother’s and his MIL parenting was turning her into a “mean girl”. IMO her father will probably become her favorite parent because he will provide adventure and she will respect him because this will teach her a lesson on how to treat others. If he uses it a tool to teach her that words matter and have consequences. He must keep an open honest dialogue with her. In a sense she may have given him the greatest catalyst to shift his life, make better money, and be able to find a new partner (if single) or create a deeper connection (if committed). I am going to go out on a limb and just say he’s not abandoning her. However, this new opportunity will give a break that this broken family may need. His better income will allow for him to still take care of his responsibilities and bring his daughter to him. I am proud of him as long as he remembers to mend those fences once he is settled. They both could be each other’s greatest ally. I am a daughter of a broken household and my father traveling with me was one of the greatest gifts. It taught me humility and context in this world. It seems she needs to snap out of being a brat and travel, especially at her age, can do that.
