AACoffee, run a country mile, if he's told you be doesn't have a drinking problem and yet he goes to these meetings in order to meet people, women I'm assuming, then he's not 13th stepping you, he's just a sad, low self esteem d**k out there preying on vulnerable people that are unsure of themselves as they try to pull their lives together cos he thinks they are easy targets. I'd have a conversation with the group leaders and explain your conversations with him to them. They shouldn't want a toxic element like him in the group messing with other people's recoverys surely?
