@Pregnantandlookingforadvice, really hope that you've managed to get some rest at your mum's place. Good luck this weekend with getting hold of your stuff. Stay strong, you can do this!
@SpaceOfAides, I completely agree with you that people shouldn't be using their kids to get back at an ex. I must add though that it is obviously assuming that the ex is someone who is reasonable, and a good coparent who behaves and puts the interests and welfare of the child first!!
With my DS's dad, he wasn't on the birth cert, but then he didn't want anything to do with us. Sent a load of abuse, and refused any sort of contact (even emails to update on DS's progress). He only resurfaced about 3yrs later (when he and OW split). I put my own feelings about things aside, took legal advice, spoke to both my family and ex's family...and we (ex and I) did a lot of talking about how he would figure in DS's life. He said that I was blameless in what had happened. I was clear that I wouldn't be standing for any of the antics that he showed me before (he and OW would throw a lot of really nasty messages at me about not wanting to have anything to do with us), and that I expected him to be polite and civil....and to not suddenly change his mind over being in DS's life just because another woman came on the scene.
In those 3yrs before ex came back, I never ever badmouthed his dad. I had photos of him as we'd been together 3yrs, and would point out to DS who his dad was. I just said his dad lived away from us (he fucked off overseas with OW). I kept things simple. I also kept every message, email, letter etc he sent me....from the lovely stuff when we were together, to the shitty stuff. Just in case DS ever wanted to see it when he was old enough. I was/am close to ex's family and would spend plenty of time with them, so DS is also close to them. Nearly 16yrs on and things are good. DS has a good relationship with his dad. Ex and I now have a good and respectful co-parenting relationship.
In the same way, when XH and I split, and I filed for divorce, he turned nasty/abusive/threatening towards me (and due to his alcohol/drug issues, was wholly unreliable and unsuitable to be having the DC unsupervised). OW was on the scene in that situation too. I applied to the courts for supervised contact for him and DC and was granted a PSO. Due to XH's behaviour, Judge also immediately ordered a CAO be put in place (DC to fully reside with me, no overnights with XH etc etc). Judge blasted XH for his behaviour at the time - it was bloody awful and I had to inform police and SS about it. Some years on, and we have managed a good/respectful co-parenting relationship.
I have never used my children as pawns. I have never badmouthed their dads to them - I have not allowed friends/family to badmouth their dads in front of my DC. I have never refused contact because of lack of child maintenance. What I have done is ensure that they can see their dads, but their Dads remain civil, polite, sober (in case of my XH!) and behave in a way that is not going to upset or affect my DC. I put my own feelings aside and have always acted in the best interests of my DC.
