It's going to look bad on Matt if she is truly dating Songkran because 1. She denied ever personally knowing him. I don't remember her exact words, but she said something like she's never spoken to him or just met him passing by. 2. Songkran didn't give Aff a divorce during the last two years because he was still pursuing her and wishing for a reconciliation. It was only this year that he finally admitted defeat and gave up.
It's timing. So if Matt was dating him this whole entire time or any time while he was pursuing Aff, it sort of looks bad when he was the one giving everyone the impression that he didn't want a divorce from Aff and wanted to protect his family. He did it publicly that there's no way Matt could have missed it.
Anyway, love is blind. If Matt likes Songkran, I hope she does what makes her happy. Sometimes, we fall in love with jerks, scum, and just messed up people, but it's those type of people we throw away everything for and become the most memorable and worth it in the end even if it never lasts. There's something about a moth that loves the light to die in its flames.
But if Matt's fans are attacking Aff? I'm sure Matt will be alright. The Thai society has gotten so bad, there are no morals anymore. People do what they want to do at the expense of others. It's Hollywood in Thailand now. The more dramatic, scandalous, and crazy you are, the more popular and liked you become. People in Thailand confuse being brave and bold with brazen and shameless.
