You'd be a hot commodity. Thailand is a very conservative culture. despite the "live and let live" attitude, ladyboys, prostitution (the last two are deeply rooted in Thai history and not seen as shameful in any way). My Thai female friends tell me of all foreigners, American guys are seen as gentlemen compared to the rough handling they get from others,
Stay out of the bars. Just get there and focus on rebuilding yourself. The availability of women to men is off the charts, and the vast majority aren't the "gold digger" stereotype. Don't bring her back to the US though, that never seems to work out well. There's a huge expat community ready to welcome you, and within short order, other guys wives will start setting you up on dates.
