Not bitter at all. It is just cold hard facts. Nobody moves to Thailand and dates an older woman. It is funny how guys pretend they choose Thailand based on tropical fruit or weather. That's the lie they tell people back home. Nobody believes it.
How so? Bar drinks are expensive. You eat out a lot. Get a partner, eat cheap food, go for walks on the beach. Join a cheap gym. Watch movies on tv. Having a partner would often be cheaper as you can stay in room more.
Not much of a drinker. Do you drink a lot? I would mainly drink with my partner. Why don't you get a partner. Then you would likely enjoy Thailand more. Most of the unhappy expats are single. Going to restaurants and bars alone would be boring.
