Welcome to GN 1wend.
There is nothing wrong with you. I'm going to say that again; there is nothing wrong with you. Keep telling yourself this because it's important for you to understand that you are not at fault.
It looks from your post, as if your ex and his wife have been systematically feeding your son verbal poison to come between you and are unfortunately succeeding.
The fact that your son has given you his new address despite not responding to any of your text messages, is a tiny glimmer of hope IMO, as he could just as easily ignored you and you wouldn't have known his new address.
You need to be able to talk about this to someone. A trusted family member or friend perhaps, or maybe counselling would be beneficial.
The hardest and most painful thing about situations like these is accepting that there's nothing you can do. You have no control over your ex's and his wife's behaviour. You have no control over what your son will and wont believe.
You say that for 5 years you've been talking to your son about counselling to improve your relationship but in all that time, he's never had the time.
Now's the time for you to take care of yourself for two reasons. The first is that by doing so, you'll be better able to deal with what's happening and the second, is that by taking care of yourself, you'll be better placed to be there for your son, if and when he needs you.
There's a support thread on this forum for anyone living with estrangement and you might like to post there too.
If you take just one thing away from my post, take with you that there is nothing wrong with you.
Take care and post again so we know you're alright
