Hi Logic, did you meet him in the end? Chances are somewhere in the back of his mind he knew he would end up watching/betting on the races but put his gym kit on to give him an alternative reason for leaving the house.
With no real signs of a commitment to seriously acknowledging his problem or taking steps toward change it is really difficult to see where you go from here.
When he ‘lost’ his wallet did you bail him out? Is it possible he had already gambled the money it and ‘lost’ it until he could get money elsewhere?
For a CG there really is no such thing as a good day at the bookies, they will normally stay there until they have spent every penny they have regardless of any ‘winnings’ they may of had along the way.
If you did met him I hope it was ok, I always found it very hard to relate to my CG when he was in gambling mode ie disengaged with quite a hard edge.
Try not to get sucked in too much and keep us updated, Lily x
