Hi Charm....i can relate to where you are coming from too. It's a real tough thing to deal and cope with. My ex and i were together 9 months (3 active and 6 sober). He left me at 6 sober, he was vauge, mean, avoiding and very very different and weird. Come to find out, it had something to do with his ex. But what i've learned and someone mentioned above, he can be a "dry drunk" which means you can physically not drink but doing everything else the same...i.e. same places, people and things.
You can take the drink away from a jerk and he's still a jerk unfortunately and that's what i found with me ex. Feel free to private message me and go and read my posts, i've been dealing with this for the past month and a half......we are all here for you
ask away, we are all listening.
