well, can't say I'm not surprised. When my ex first started to go to AA meetings, he told his friend "There is a hot blonde in my meeting and I'm going to take it slow with her"
Him and I were still very much together at the time
The really sick ones can/do use the meetings as a place to hit on women.
The ones who REALLY want recovery, would not dare do this.
Even if your ex is telling the truth or not, get yourself to an Al anon meeting to better understand your need to fix (we all have that here) and to help understand her sickness.
