Note: All of these questions are regarding a male ISTJ, in case it makes any difference.
What qualities do ISTJs most gravitate to in others? (In regards to a romantic relationship.)
How important is another person's physical appearance to an ISTJ?
How do ISTJs respond to unrequited love?
Are ISTJs generally self-conscious/afraid of seeming creepy when talking to someone they are interested in romantically? Do they frequently (or ever) worry that their person of interest does not like them or does not trust them?
Are ISTJs at all empathetic to other people who are shy around THEM?
Is it typical that an ISTJ would greet his hopeful love interest with great enthusiasm, but if said love interest ever greets HIM first, he would respond shyly?
How big of a deal is it if an ISTJ shows a consistent interest/concern in another person's feelings/emotional well-being?
How likely is it that an ISTJ would be asked out by a good friend who they do not have romantic feelings for, but the ISTJ dates the good friend anyway out of pity, even if they are not interested in anyone, or have been romantically interested in someone else for a long time (but believe that their love is unrequited?) Could this be interpreted as an attempt to maintain "order" and "balance" in their lives by not hurting their friend's feelings? If the ISTJ tries to keep the relationship a secret, is this a clear sign that the relationship makes him uncomfortable?
There is a very long and complicated story that goes with all of these questions, but I didn't think anyone would want to read all of it, so I just bring you many questions. Sorry for all of the text, but any help or advice would be greatly appreciated!
