Jennifer68 I am so very sorry to read this. You have partly answered your own question. You say he has hit rock bottom many times on the one hand and then say you will never kick him out on the other hand. He hasn’t hit rock bottom whilst he has a roof over his head and everything that goes with that. Sadly, we have all been here and it’s only when you realise that you are enabling the addictions by providing a safety net that you get the strength to ask them to leave. Every professional I have ever talked to from psychiatrists to psychologists to drug and alcohol counsellors say the same thing. Do not enable, do not feed them, do not provide a safe place, do not pay their bills etc etc because whilst you are doing that they are very unlikely to seek help. I am sorry if this sounds harsh I don’t intend to be, I have learnt the hard way, years of enabling my son which in turn made me and many of us on this forum ill, physically and mentally.
I can only advise you to seek professional advice for yourself to help you make informed decisions ones that aren’t affected by the emotions that come with being the parent of an addict.
