I'm not going to jump in to support my SO in her AITA thread.
Why are not going to support her?
I lost trust in her ever since she worked with XDA.
You've lost me. Why in the world would her associating with a mobile software development community make you not trust her?
You don't understand...
That's for sure. Is it because you're jealous she putting energy into something other than you? If so, you should get into counseling.
