Tempting to text him back “oh I bloody well understand now! I’m just not buying what you’re selling!”
But I agree perhaps best not to get into it.
BUT don’t believe it - it’s bullshit!
Sort the financial and legal stuff and don’t treat him like a friend - he is no longer an ally!
Don’t lie for him to the children either, he didn’t call - you don’t know why don’t embellish in a way that helps him. It’s not actually doing them any favours, my dd was really upset with me for covering for ex says she wishes I’d been honest from the beginning. Yes in an age appropriate way but honest still.
At 13 and 15 they’ll soon catch on to the reality anyway and they need to be able to have complete faith in at least one of you that they’re not being kept in the dark. My daughter was 10/11 when she caught on and started asking ex some very awkward questions!
Your head and emotions WILL be spinning right now that is normal but be careful what you do and say that he knows about.
Get recommendations from family/friends for a good solicitor (they aren’t all good) you need someone assertive and pro-active and who won’t stand for nonsense from him. This will also hopefully get you some real life support which you do need.
And yes start claim for cms today as they only backdate to when you first claim. Ditto council tax single person discount and any benefits you may be able to claim as a single parent. The sooner you get the ball rolling on these things the better.
“It’s like playing bingo” it’s nuts how close he’s sticking to it - bet he thinks he’s oh so original too! Ha!
So glad you have sensible supportive people in your life. And it goes to show you hopefully given their reaction that people who know you both don’t for a second think you’ve done anything wrong and he is indeed being a selfish prick!
And yes - them coming sniffing around you a few years later is part of the script too in my opinion - mine propositioned me the night before their wedding!
