Is it sufficient?

1. I had to ask for her new phone number when normal couples gives their partners their new phone numbers when they travel to a new location.

2. I've mentioned four times I'm traveling to Singapore, not a single offer to want to see me/stay with me/let me stay with her.

3. In the past, I stayed with her at her house and she didnt offer me anything to drink/snack. Instead just started snacking on her own. Is this normal hospitality?

4. I asked a simple question to her company's communication department and suddenly I'm an enemy, a suspicious person. (The question was regarding transportation to and fro Singapore mainland and an Island off.
