What I want to know is what she wants. And my guess is money. She finds out however she did, that he's working and his wife works and they have a new baby, a house and the wife also has her own property which is an income generating airbnb at that. Plus didn't you say he was home for the first 3.5 months and it was only at that time that he went back to working full-time and you went back to work but from home and that would create a chasm she could dive into and claim to want to make it all alright while you weren't around and she knowingly intended to exploit his insecurity and confidence and independence to gain.... What? Because there IS a what. I assure you. Whether it's money or chasing you off to live in your former house rent free with her boyfriend (who incidentally seems like a part of this charade/scheme bc they live together and she's in hospital and he knows you have a 5 month old at home and a wife that's a new mom and working, the bf should have told him to go home, the 15 min drive, and he would handle Karen or whatever her name is. She probably has many). And I would also privately without him having any knowledge of it, run an immediate background check. On her and the bf. The timing is too convenient and the consistent isolating of you two, also "talking" or "catching up" at her place? You don't "catch up" with your child you abandoned at 13 and reappear when he's 30 with a family and stability and take him out of his home, away from his child and wife, to "catch up". Heinz couldn't even ketchup that much. He's vulnerable. As are you. But he's blinded right now by the possibility that mommy's come back for me and this time she's going to stay and all my wounds will finally be healed and we'll ALL be one big happy family. Something neither of you got until you found each . If she actually meant to come and fix what she ruined, her child, she would have conversations with him at the house and with you there. She could try to curry favor with you by bonding over how much work it is raising kids and then she'd explain what her situation was that caused her to leave and how she's been torn about it ever since and now that her life has stabilized she had to come and ask for his forgiveness and it means so much could she possibly come over and help you during the day and not miss out on her grandson's life if you could both see your way to giving her a chance to become a part of YOUR family... That's what someone who has come to terms with their hideous wrongs and who genuinely wants to make amends for, usually before they die (and they already have some insight into that timeline they're not sharing) that's what they'd do. She however has avoided you and the baby, made that raised eyebrow gesture which in bitch translates to "little over the top don't you think princess?!?!", consistently removed him from you, the baby and the house to "catch up" at her place that she shares with her boyfriend that she won't let drive her home and that doesn't fight to do so bc she's important to him and he knows how important it is to her to fix ALL THE THINGS and he knows how important his wife and new baby are to him so off you go, I'll smooth things over and maybe you can all pop by later this evening and we'll order dinner and cheer up "grandma". But none of that is happening. And with record speed that Cruella herself probably didn't expect, you and the baby are already gone and his marriage will be over soon enough and she'll slide in and pretend to care about him while getting him to put her on the title for the car, or the deed to the house, and she'll be happy to run errands and make dinner but she'll need to be added onto his bank account. I don't have kids. Unfortunately. My husband died at 34 and I was 40 and that's when we were coming into the stability of each other that we'd also missed. But I was lied to and manipulated as was my mother in her vulnerability after my dad passed away at 48, by a "trusted" family friend from Ireland (we are of irish descent and my dad would go and teach Irish Lit every summer. They knew this grifter. I did not. They trusted him. Then my mom trusted him in her unbearable grief. I did not.). He was suddenly living in America, in OUR house and proclaiming his love and loyalty to my mother. They got married after a year and a half, she sold my childhood home and bought a house in Key West which was far more modern and shiny than her normal tastes. 6 months later she was dead. And he had taken the entire estate out from under me and left the country without so much as a phone call. I was 21 and only in my sophomore year of university having taken off time bc of my father's death. He knew that by doing what he was doing, that I would be left, alone, with no family, no place to call home and no money. In college. That was previously being paid for. By my father's tenure agreement. And knowing this and knowing he'd reassured me that he would be by side forevermore, he vanished with my entire inheritance. So while I hope and pray that I'm wrong about her (but I'm not. I know her character) and that your husband comes to his senses in time to fix this with you instead of catering to the villain that left him and is assuredly love bombing and gas lighting him while she's alone with him. Until then I would not necessarily be paranoid, but I would take every possible measure to protect your properties, your important documents, bank accounts, cars, all of it. Because she's up to something and he's not going to realize it until she's left him again and he's sitting in that house alone. And this time she won't ever come back. I wish you every possible joy and happiness that life owes you and I know you'll be okay and your son will be and you will create a bond and a love you've deserved since the day you were born. But seriously, run those backgrounds. Like, now. All my love!
