Aaaaaaaarrrrrrrggggghhhhh
The sidecunt has dumped him.
He's lost her, his job, his home, his reputation, his marriage, your and probably his parents' good opinion
There is no man so loving, persuasive, etc as the man who needs somewhere to live.
This is love bombing time, designed to push your buttons by temporarily supplying what you still crave, as a means to an end. This is emotionally abusive behaviour, targeting you where you are most vulnerable.
He has temporarily strapped the slipped mask back on, the one you and your daughters believed, loved, wanted to be real. He's now capering around in front of you all, holding it in front of his real face chanting 'See? No don't look under the mask - the mask is meeeeee ... '
Have you ever seen Chitty Chitty Bang Bang - the Childcatcher in disguise, then revealing himself?
Because what lies beneath is the real thing, and no matter how much you WANT to believe the disguise - It. Is. Not. Real.
For your children, though, it may be enough. I'm sorry, you're going to have to be the strong one, the difficult one. The one who says No - to them all.
He was never a 'good father'
A good father is a man with loyalty, fidelity, morality, trustworthiness, compassion, kindness to his WHOLE family.
A good father doesnt lie, cheat, deceive, insult, humiliate the mother of his children while fucking some thieving bitch who knew what she was destroying, while he was playing nice to the kids to get them on his side, or doing his actual duty of sharing the childcare, or whatever it was you're clinging on to. That was divisive, manipulative behaviour in itself, separating you from your children's attitude to him. Isolating you.
You may not have bruises and broken bones. But your mind has been battered and hurt.
Don't agree to couples counselling. It's another of his mindfucks. Instead, invest in some therapy for yourself, to help you heal from what he did to you.
If you take him back, much as you desperately want to, you'll never be able to trust him, because you know what's under the mask, what he really is. Anxiety, suspicion will haunt you and leave you in a constant state of worry. What if...?
And the shitty thing is, if he manages to keep the mask up, you'll then appear to be the crazy one to your children, family and friends. 'I'm rather worried about her,
we went through a difficult patch recently but we're good now but honestly her behaviour is starting to worry me and the children ...'
Get the therapy. Heal and find yourself and build a home for yourself and children.
Say No. He needs to get a job, meet his support duties, find a flat and create his own relationship with the children. One that doesn't involve manipulating and abusing you.
