Do you think its fair for a dominant person to ask a sub (who is not his own) to request tasks without meeting them?
If the sub is NOT his own, no - it is not fair and it is certainly not okay. From reading your post, love, I can see through your writing that he had no respect for you as a sub - let alone as a human being.

Am I being too judgmental or closeminded by not obliging him?
No - you're being the intelligent woman you truly are. You made the right choice in this matter - do not for a single second think that YOU were in the wrong.

Im very biased on the topic so I thought Id get some feedback cause I did start to wonder if I was right to stick to how I felt, and not allowing myself to be pushed... I have a lot of conflicting feelings about it right now, and thought itd be good to get some more opinions. What you think?
You were absolutely right to stick to your gut feeling and to trust yourself in this. Even as a sub the prospective Dom/me has to respect your boundaries and work slow with you to establish your trust and understanding within you both. If someone is to push you... you need to trust them and have a long established relationship (friendship) with them. This "Dom" you speak of clearly disreguarded your wishes, your trust, and your boundaries and failed to recognise your reasoning in this matter. As TW said - "I'm the Dom - do what I say" ... HA! I do not think you have a single reason to hold conflicting feelings - you trusted your instinct. That is enough.
