I'm a father who done a CL for one of my daughters, to try and safeguard her and her children. There was previous: there was lovebombing & coercive and controlling behaviour, culminating in my daughter leaving (him and his house) a week before she gave birth to the mans child, and seeking housing from the council.
She is reconciled, back with him, I stand accused of being selfish, only thinking of myself. She told me there was no abuse, there is no abuse, bullshit i say on the former at least.
Do I regret doing a CL? I cant really because no father is going to ignore what I'd previously evidenced. I paid a big price, estranged from my daughter and thus by default my grandchildren.
OP, I wish you all the best, if it turns out he's a bad one please don't let him reel you back in. If you're with a master manipulator/ possible narcissist (like my daughter was/ is) they reel you back in, they are experts at that, all nice until the switch comes again, which it will.
