I called him after the gym and was LIVID and he totally disarmed me by saying, "I got up this morning and went to a meeting." This was his first meeting, and something I'd brought up months ago but had not harped on in the interim.
He hasn't gone to any more meetings since then
I just wanted to add that the reason he has not be making any more meetings since then (if he ever even went) was because you had mentioned meetings in the past and he used it as a pacifying tool to manipulate you and it worked!
Alcoholics who find themselves in a fox hole are excellent at manipulation.
If he had been real about meetings, he would have at least made a few on his own.
As far as being lonely, if he went to meetings he would make new sober friends. You do not have a responsibility to alleviate his loneliness which is probably more a case of isolation (alcoholism thrive in isolation).
