I guess I am asking what other people do as coping mechanisms.
My marriage thankfully ended 7 months ago, because my stbxh is a mess. He has a drink problem, associated depression, big mood swings. Since the marriage ended he has lost really well paying jobs twice because of his erratic behaviour, and is living with his parents. He initially moved 150 miles away from us, and left us without a penny or any support (I was a sahm). I have managed to apply for state support and moved 180 miles the other way to live near my family for emotional and physical support, and some financial backup. My x has not had a parental role with our young children in that time and has not wanted to. He has seen them once in over 4 months now. (He could afford petrol until he was fired again last week). He calls the children daily (when he is not busy) on my suggestion, but they seem to be there to entertain him and conversation is limited. Now that his work life collapsed again, he has suddenly started inundating me with emails (these periods go in fits and starts, but in 7 months, I have had over 200 emails, many texts, had to turn whatsapp off on my phone, he calls children daily) and he out of the blue told his 3 & 5 year old on the phone yesterday he was coming to see them the next day afternoon, not having said a word to me and not having wanted to see them for 9 weeks. I felt terrible having to say no, but we are not even at home...
I feel really unsettled and stressed because of his mood swings, and I guess am being badly triggered by his behaviour (as during our marriage I coped very badly with that, he was habitually absent, drunk or suicidal for many years and as a result I was not able to set any boundaries down I was too scared he would either drink or top himself). I am frustrated because I am scared about the effect he is having/will have on the children if he can't start being more stable around them. I am upset because I want a clean divorce (he won't sign the papers) and I really need to move on with my life. And I can't work out whether I am still enabling him through guilt and shame feelings, or he just doesn't listen to any boundaries I set down anyway.
His best friend and parents are all really worried about his behaviour too, so I don't think I am overreacting. But I just don't see how I can move on from this situation, it is a nightmare rollercoaster. It affects my calm around the children which upsets me so much, it affects my ability to move on as I end up so anxious. I have already had a year of therapy to try and detach and it did a lot of good.
Any advice or straight talking that I need to hear? This morning I just can't see the wood for the trees. Half the time I feel like I am crazy and I have invented all of this. (I was told often by him in my marriage that I was mentally ill and abusive towards him, he also moved us annually and isolated me from my friends and family because he told me they had caused his and 'my' mental issues). My therapist told me I was there was nothing wrong with me, other than being stuck in a situation I couldn't get out of by myself.
