Hi and welcome to beyond blue. This is a safe and caring space and you will be supported by the users her while you are here.
I am thinking that things have not turned out the way you planned. At this minute there is not much I can say that would make you feel any better. Except that I am listening to you tell your story.
Sometimes when you write it all down somewhere, like here for example, the answers to your unwritten questions might reveal themselves. Whether you do that herer not...
Do you have anyone you can talk to also? Family? Friends?
And I guess I have a question for you... What do you want change?
With all of that said wondering if you might be able to send a letter to his parents about the effect this is having on you and the kids? Or have you tried this already?
Peace and blessings,
