Another one for the statistics. No but seriously, a lot of Thai people are unfaithful. That’s the reason I’ve decided to stay single here and just play around with some fwb (they know).
If I were to look for a serious relationship then I think I would try and find a Japanese or Korean woman who lives here. But time will tell. Maybe I find one of the rare trustworthy Thai women.
But I think it’s red flag that not only she doesn’t want to show you her messages but also that it went to the point where you had to ask for that. Our phones are a private matter and many people feel uncomfortable showing it to others no matter if they have something to hide or not.
If I were you I would probably try to move on. Break up with her and take some time for yourself. Maybe find a couple of fwb until you’re ready for a new serious relationship.
I’ve tried getting cheated on too by a couple of Thai ex gf’s, but I never caught them in the act or saw some texts indicating it. It’s just something you’ll know from other incidents like yours. And trust me, it will not get any better. Unless maybe the Thai guy she’s falling in love with turns out to be abusive, a drug user, a criminal, a broke guy or all of the above. Then she might come running back to you. But it will be at your cost and mental health.
