OP 'tough love' straight talk coming up. What I see is you making him out to be a long suffering man.
I can imagine having to move in with me and my daughter, having a baby and a really fussy one at that has been challenging.
and
He didn’t give up on me when I suffered my ptsd. He didn’t give up on me and my daughter as she struggled with seeing her dad and her behaviour was appalling towards him.
The poor, poor hard done by man. He didn't HAVE to move in with you and your children, he CHOSE to. Know who didn't have a choice with this man moving into her home, disrupting her life, turning her life upside down and also reminding her of the father she can't see? Your DAUGHTER! You make out like this man is a saint for putting up with your daughter. Did you ever, ever, JUST ONCE, think how difficult it is for your daughter to put up with a man in her house, and have her home, her safe space, overtaken with his junk? Did you ever stop to think about what she has gone through and sacrificed, just so you can have a man? She is, naturally and understandably, lashing out at the man who has invaded her safe home when the she can't be with the man she wants; her father! And you think this other man is a saint for 'putting up with' your daughters understandable emotional trauma? You're not real!
It's hard enough her having to deal with the absence of her father, she now has to deal with this man moving into her home, with all his garbage, and THEN being made out as if he is a saint for the pure privilege of him doing so.
You really don't stop to think about your daughter, how she has had to deal with this man moving into her territory and disrupting her life and what she has had to endure, do you? You've got the saint/villain completely the wrong way around. And you wonder why your poor girl is acting up. Put your daughter first before dick. You owe it to her. You've been told repeatedly to live in separate houses. By everyone. You are simply not listening. You keep posting away whimpering and complaining. You asked for advice. You've been told what to do. All you said was you 'asked' him if he felt better at his house. Not even told. You've been told to send him back to his house. It would be a win for you, a win for him, and most importantly, a win for your children. You keep posting away, ignoring us and making excuses for him. Btw, your bar is so excruciatingly low. If he loved you, putting up with your PTSD is the most basic bare minimum. So now you feel you owe him for him being a semi decent man, instead of putting your health and your children first. Your bar is subterranean. FFS act on the advice you were given, send him back to his house, which is why you asked for advice otherwise we're wasting our time.
