I don't think a relationship means captivity, least not to me. I guess I don't relate to this common ESTP thing, maybe more related to 7.
Your odds for putting me into captivity would be higher.
You will hate me for saying this, but it was a bit 'demisexual' of you🤷♀️
Maybe I came on too strong with the marriage proposal
I think you are maybe misreading this part (ordinary person). In general I experienced this as a very good sign in a male interaction. Superior/inferior is not a good sign.
I don't know if you are like this, but I like ISTPs because they do seem like pillars of strength. And they are doers with a healthy sense of freedom and independence, which I like. Plus they are usually quick with the jokes and commentary, which you are too. And they can become good teachers and mentors when they mature. But there is nothing ordinary about ISTP lol. Solid maybe. But ordinary, definitely not.
