He really needs to be the one to go to these groups – he needs to get help, this early into your relationship it should be healthy and happy.
I know the feeling its the absolute worst thing, the thing is, you leaving him so early on, day 1 of his withdrawal i think he may relapse, I would personally be there at home with him but if you feel youre needing help i am not sure what to suggest.
His mental health is going to be pretty bad at the min, so he’ll need all the support he can get. I am shocked hes not got any help from the doctors if i am honest.
let us know what happens xx
