Longines - any advice on how you have dealt with this please
@Chumbaw, I'm still working through this to some extent, but the things that have really helped me are (1) counselling to vent and to process and understand my own feelings, (2) learning about boundaries and starting to recognise where I want my emotional boundaries to be (and how far over the line they were before!) (3) having sat in on some of my DD's CBT and learning about unhelpful thought patterns like mind-reading and predicting the future, etc that feed in to establishing emotional boundaries (e.g. catching myself when I start viewing things my ex does from his perspective as a selfish arsehole and turning it round to think "ok, this has happened, how does it impact me and the kids and what can we do about it?", and realising when I think "there's no way he's going to agree to that" that I'm shooting myself in the foot by assuming he won't do whatever it is, because then it becomes my fault he hasn't done it instead of his).
I've found that recognising that my own overarching feeling driving my anger towards him is not that he's a bad father and left us high and dry (despite that also being true), but the fact I often feel unsupported. If I didn't feel unsupported and we were thriving, I wouldn't give a shit about his motivations or selfishness. The only reason it becomes an issue for me is when I'm looking for the root cause of my unfortunate predicament. So rather than focus on him, I focus on changing my predicament. For me, that looks like getting the help I need from the council and getting advice and signposting from charities and CAMHS to make sure the DC have can have a good life and get all the support they're entitled to.
When I start feeling hopeless or angry, I remind myself that I'd rather my DC have a good life despite his fecklessness than a bad one because of it, and I ask myself what I'm going to do about it.
The other thing that has helped me massively as a mantra in terms of keeping boundaries in mind and not going off-piste emotionally is the serenity prayer: grant me the serenity to accept the things I can't change, the courage to change the things I can, and the wisdom to know the difference. Before, I was mistakenly trying to change my ex and getting frustrated that I couldn't. Now I'm ok with his idiocy (after all, arseholes gonna arsehole) and I direct my energy elsewhere.
