More will be revealed to you soon enough. Really, witness his actions and try not to put too much hope on his words.
It is not that many of us here at SR are being negative just seasoned with the behaviors of alcoholics/addicts.
My ex could have written a handbook on how to manipulate, deceive and con anyone into believing he might really go to rehab and that he really wanted to quit. He was so good at his con he even got Dr’s to write him prescriptions for Xanana to help him with anxiety while he attempted to quit. The sad part was he told the Dr’s he was an alcoholic and was attempting to quit drinking when all the while he was a pill head over using Xanax and found a new con in order to obtain them.
