Dear Romana,
I suspect that you are right and your boyfriend is trying to manipulate you. You are a lovely sensitive person and he knows it.
He appears to be trying to put the blame on to your shoulders by saying that you failed him in managing the situation. These are not the words of a man accepting he has an addiction or is even preparing to begin to take responsibility for his actions. What has ‘he’ done in the last few months to manage his situation, has he gone to GA or sought counselling?
Has he now left to go to an hotel or was this just more words? If he has left then you are not responsible for him. If he sinks deeper into his addiction it will not be your fault, it will be his choice. He can save himself but he has to want to do it.
Please keep posting and maybe join me tomorrow evening in a F&F group. Its horrible when you have nobody to talk to but I will be here listening and I do care, you are not alone.
Take care of yourself
Velvet
