Welcome to SR debpug, Im happy you found us...
Does it ever stop or get easier??? Yes it can get easier and you can find some peace in the middle of all this but unfortunately you have to work at it. When the addiction was at that point for my ex I had to take action for myself or get sucked down with my A. I was going crazy ... just as crazy as he was.
I started attending Al-anon, reading everything I could on addiction, open AA meetings, theraphy and here at SR.... I learned to detach with love from my A and the tools to set some serious boundries and stick to them. My ex and I did not make it but the last I heard about him he was sober.
I look forward to getting to know you... stick around, keep posting and reading. You dont have to go through this alone hon.
