You realise, of course, that many people occupy the position of both crazy ex and step mum?
To me, the idea that the 'first family' has priority is ridiculous and way outside my experience (and that of anyone I know who is also divorced or separated). I am frequently reminded that my ex is a 'good man' simply by virtue of him seeing his children regularly. That I arrange all childcare, take time off work to deal with illness, do all appointments, arrange all holiday care, and the big one...actually pay for everything (he won't pay maintenance and gets away with it as he's self employed) means nothing at all. In fact, should I dare to say anything I immediately take up the position of 'the crazy ex' who should know which side her bread is buttered and stop bothering decent people who are just trying to get on with their lives. I mean, seriously, who on earth do I think I am expecting my ex to take some responsibility for the care of his children?!!!
What I find particularly worrying is that it is frequently women who stand behind him, egging on his bad behaviour, quite happy to tell me that I'm a 'grabby bitch' when I quite clearly can afford to support my children myself.
My ex's 'second family' by far has the best of him from a practical, financial and emotional perspective. Our children are forgotten amongst his anger and hatred of me because, you know, I dared to get on with my life rather than fight for him (he still - 8 years on - has no shame in asking me why I 'didn't fight for him', like any human being with even the tiniest bit of self esteem would want to continue to be with a man who cheats with other women and then refuses to support his children').
You should also consider what it's like to a child who is viewed as an inconvenience or nothing more than a visitor in one of their parent's homes. Or to be cared for by a resentful step mother who hates your very existence rather than actually deals with the fact that her issue is with a partner who expects to be able to palm his children off on her and for his life to continue as normal.
Not a psycho-ex in sight as far as I am concerned.
