Thank you for all your messages.
It really doesn't help being called 'names' - although I do appreciate that some feel strongly about this - calling me a disgusting mother and whatever else, doesn't deal with the depth of my emotional distress and inadequacy that I am a) in this position (again) and b) struggling to 'escape.
Obviously I know what I have allowed him to do is wrong - I would not have posted here if I thought it was all ok, but a situation does not arise from nowhere and in a vacuum. I have allowed things that I believe to be wrong, to happen in my house, because I do not have sufficient faith in my own judgement about what is right.
That issue will still be there whatever I do. And I need to address it. I may need to address I before I can act, because right now, baying women are telling me to 'get rid' , but I have obviously not presented the full picture.
And again I KNOW this is wrong. Forget the finances for a minute, the behaviour to the kids is wrong.
DS1 is/ has been 'difficult'. The predates DP. He lies, habitually and always has, from 5 years old. Even on the face of incontrovertible evidence he will continue to lie. We have been to mental health experts, therapists, educational psychology. He is just like that, and I expect he always will be. He is my son. I love him, and I forgive him. But I do not trust him. He has stolen from me countless times, from his grandparents. he has stolen form friends and family, He was expelled from school, and has been arrested for drug possession. He is my son, I love him, but I don't trust him. This is HARD to live with. And it gets harder as he matures. He will lie even when there is no need to, and he lies to EVERYONE ( there are some women who post about partners like this and I have great empathy).
DP has been good to him in the past. He has attended school with me, been to the police, talked to DS1, taken him camping, on days out, on weekends away. he has taken him clothes shopping to gigs and to a festival. He has done a great deal more (and I mean with a good attitude) than DS's father has. In the last year he has 'had enough'. I understand this although I do not condone it. Several of my friends will not have DS in the house because he has stolen form them, my own brother has him on a 'last warning' because he has stolen. Lying and theft destroy trust in a family. I think DP's reaction is extreme, and I think it is wrong, but I have no better answers - or I have not had - and I have been at the end of my rope too.
DS2 has only ever really know DP as a father. They are very close. DP is quite tough on him, but no more than eg my brother (who is a great dad) is on his son. DS2 does quite often watch movies with me /us. he uses the living room for music practice and homework also. Again DP has done a 100 x more for DS2 than his own father.
He has been, in the past, very emotionally supportive to me. That may sound ridiculous, but he gave me courage to negotiate a reasonable divorce settlement - rather than being walked all over - the courage to deal with an unhealthy work situation and confront it.
My issue is with my own boundaries and my own self belief. I have conflict and have put up with far to much in a variety of situations and relationship without recognising when it is trampling over what I believe. Why is this ? I honestly don't know and it is not my public persona at all.
In writing here I am trying to order my thoughts, find my own boundaries and my own beliefs. I have seen fantastic support on here. I'm asking for ideas and help.
Once again. I KNOW this is wrong. But kicking him out is one thing, avoiding doing the same things AGAIN is probably where I need help
