I came here looking for hope, my exA was doing more to sort out his rubbish than yours, 8 weeks rehab programme that he had entered voluntarily.
I've put up with the lies, he's messed with other women but he'd put his arms round me and I soooo wanted to believe that everything would be ok.
Sometimes it is but not very often, it's a tiny percentage of A's that see it through and get sober and to them congratulations to a job well done but this isn't the norm.
I'd known my exA for 16 years, thought the drunk thing was a passage of youth but it wasn't and got far worse. He was drinking far worse 4 weeks after rehab than I'd ever seen before but had all the "treatment" words to make it look ok on the surface. No one makes the ""runaway comments foa a bit of a giggle, it's just that we've been there.
Look after yourself and come back here for support as and when you need it
