Ill probably get flamed for this but these threads depress me.
I think it's a bit like the infidelity threads when the OW is frequently blamed letting the h off the hook.
In the stepparents threads the dh in question is rarely perceived as wrong or is innocent party. (I actually do not believe there is an innocent party in a marriage break up).
The SM often believes the h's propaganda (which I can understand tbh) about the ex wife and thinks he's superdad. And the exw is soemtimes portrayed as a loon(hope that word isn't offensive to anyone) or negligent. Wheareas in some cases this may just be a difference in parenting styles.
FWIW I am an exw and quite sane I think
. My exh has new p and new dcs all fine and I have encouraged that relationship. Until recently I channelled all communication through him and took a complete back seat regarding her.
I know that dcs will play one parent off against each other but my dcs kept coming back saying that new p had been saying to them 'mummy should be doing this, mummy should have done that' referring to things that actually he should have done in 'his'/their time with them.
Exh clearly had not put her in the picture about our arrangement and it suited his purposes to have us both in the dark. He had also never introduced us despite my requesting it.
Although I might have mug tattooed on my forehead enough was enough (im generally pretty accommodating), as during 'his' weekends I was still doing lots of running around in the car and also because of the reduced time he spent with them (often the new dc's routine was used as an excuse) also finding lots of extra food etc. and I told him I would contact her direct with details of our agreement so she could be fully informed.
As I saw it by doing all that I was enabling them an 'easier' time of it and that he wasn't stepping up to the plate. My dcs are also hurt when he only sees them for a 24 hour period over every other weekend and said that the new dcs needs appeared to be coming over and above them.
Apparently she was furious I had dared to even contact her and about the content of my very bland email and he persuaded her not to reply.
I dont envy her situation but the bottom line is that if I don't feel he is sticking up for our dcs and also allowing them not to be treated age appropriately then I will have to intervene.
I think that many exw will only have their dcs best interests at heart which can cause friction between the two families.
Also teens are difficult to parent by anyone and if you had smaller dcs you couldn't imagine that yours would ever grow to be like that!!
