Does it seems that my supervisor was reluctant to let me go for conference? I have already finished the first draft of my thesis and now I'm reviewing chapter by chapter. A few days ago I submitted my abstract to a conference and was accepted. I emailed my supervisor and asked for permission to go for conference, but she didn't answer. From my experiences of working with her, she didn't answer means she didn't want to answer and she didn't agree.

I am confused at the moment why it happened like this. She always spoke highly of my work and told me that one of my results chapter can already been made into a journal article. So I'm wondering if I should ask her before submitting my abstract?

Do I have to ask my supervisor first and submit the abstract? Do I include my supervisor's name in the abstract? I'm working in the field of humanities, and I collected and analysed the data, but she involved in the research design in my early stage and now she is giving me feedback on my writing. 

So I really want to know if it's just she didn't want me to go for conference or my unethical behaviour offend her? Shall I ask her in the supervisory meeting again for this issue to figure out what's the problem?

She may not have answered for many reasons.

If you want her to fund your attendance, then yes.

It sounds like she's a co-author, so yes.

Again, she may not have answered for many reasons, but you require her permission to list her as a co-author and you may require her funds to attend, so you should have probably asked her first.

Yes.
