OMG. I'm so sorry this happened. What a f__kwit. The whole thing is total BS and it is absolutely not okay to use a two year old child like that. And the poor kid was sitting in the car listening to him say these things to you, too.
I'm sure your L will have good advice for you, but to me there is a pretty slippery slope between this behavior and kidnapping. The things he said to you-- basically you wouldn't give me what I wanted-- overnights with S2-- so I'll just take them-- is terrifying to me. I think if you're able to keep S2 in your custody and not let him be with his dad alone until you have a legally enforceable arrangement, I'd do that. He lied to you about an important thing involving your child and where he was. What stops him from lying again? What's the next step for him in "getting what he deserves"? Scary.
Best case scenario, this is what it takes to move the process forward in ironing out a legally enforceable plan. Stay strong. You're a great mom.
And I know you know this already but it bears repeating... you are so. much. better. off. without this a$$hole as your H. What a sad and sorry jerk. I am delighted by your balloons and pettily glad they bothered him so much. Even though you're above that, I'm not. bahahahaha.
