RedStripeIassie "He has changed all of this. He starts a job next month." Sorry but people may well change but not in four months.
If you go back with him you are putting you and your dd at risk.
I completely agree with SadGuru "OP you talk a lot about your vulnerability but don't seem to appreciate that your young dd is a lot more vulnerable than you. I'm sorry to be blunt, but this is the kind of situation that would trigger a safe guarding alert. I'm glad the therapist is putting your very young dd's needs before your own needs."
You seem to be relishing the idea you are in charge. "He will be getting therapy soon. It's one of my 'rules' for getting back together."
Maybe it feels like it now but just remember his incentive to get back in with you now may be fueling all this 'good behaviour' (if smoking dope is really good behaviour). So once he gets back in with you, what incentive does he have then?
Why not let him start the job, start the therapy, see him on dates if you wish to, but do not bring him back into your home with your child.
I was going to say that I hope you do not lose your child because of being in an abusive relationship with this guy, but actually I think you should really think now, if you want to even risk losing your child for a man who has treated you so badly in the past.
Please be smart, the only way you stay in control is to control who lives in your house with you and your child, who has input into her life and your life.
You do not owe him a thing! And neither does your daughter.
