Oh goodness, I really feel for you that you can still be low enough to consider going back
You are worth a million times better than any abuse, everyone is, we all deserve to be treated with the utmost respect and should treat others the same way.
I have been through an abusive relationship, and had 2 children with the guy, I didnt think my DD had really picked up on much of it but the change in her over the last two years is amazing.
Please, to anyone considering entering back into an abusive relationship, for you and your children, do not ever settle for being less than someone's everything.
The only time I would ever say 'try it' would be after some hardcore therapy, together and seperately, I used to think it was me that made xDP the way he was, so why do I not make my dp that way now? and why is exdp the same with his other girlfriends???
Also if anyone were to 'try it' please not at home, with children about, you can date for long enough without making it a live-in arrangement, and you will soon see if those triggers are still there.
