Dear S:

Reads to me that studying in the U.S was and is his passion, what he wants most in life, his main focus and only focus.

So his mother agrees for him to study in the U.S- he is definitely not going to risk that by fighting with her about you!

I imagine not only didn’t he argue with her about you, he probably accommodated her position about you, promising her that indeed he will let you go and remain in his past.

The betrayal is about not letting you know early and clearly that this is the case. He wasn’t honest with you, so yes, it is a betrayal.
