he wants me to come to his AA meeting (he says hes been to one)
Like fuck he has. AA meetings are closed to non-alchoholics; relatives/friends/spouses/dps can attend Al-Anon meetings and may be invited to attend an occasional open AA meeting only after the consent of all alcoholic members who may be present has been obtained. Ask him who his sponsor is, why dont you?
Or, preferably, see the lies he's told you as the calculated fiction he's created to tug at your heart strings purely so that he can return to his cushy former lifestyle until the ow takes him back, or another one hoves into view, and don't bother to enter in any further conversation with him.
The fact that there are no dc, Ma, makes it hard to understand why Starting, who is in the enviable position of being in good health and owning her own house in an idyllic part of the UK, and who has a loyal canine companion, a car, and a bunch of new friends she's met on this board, should be wasting any more valuable time on a shit who has no compunction whatsoever about shitting all over her.
FGS get some perspective here, honey. As AF has said, every second of every day thousands of men, women, and children, die of cancer, starvation, violence, and being mowed down by the armies of despots. In contrast you are blessed, and once your career is motoring again you'll have little time to engage in endless headbanging and handwringing over a deceitful twunt who's shown his true colours and who won't be changing his spots in this lifetime any time soon.
Until you're back at work, get volunteering to help those less fortunate than yourself and start counting your blessings and your good fortune, which will significantly increase once you've divested yourself once and for all of a worthless turd who will only ever be a massive drain on your emotional and financial resources.
There's no shortage of good men in this world. Set yourself free to be all that you can be and the law of attraction will ensure that one, or more of them, is drawn to you.
