My husbands dad just up and left this morning. He left the phone we paid for and the spare keys to my husbands car. He didn’t even know my husband until he was in his early teens. My husband is so heartbroken and now my daughter has to go from seeing her grandpa everyday to not seeing him at all. I’m super upset and pissed off. My husband has been depressed all day and blaming himself.
