This is probably a stupid post, but why not?
INFp's are complex creatures; we are very sensitive to emotions, and we tend to get emotionally attached to our partners. We seem to have a need of connecting with the other person on a very deep emotional level in order to be truly happy in our relationships, or it feels weird. I could see where something like this would scare the ESTp off, so I was wondering how this actually works out with ESTP-INFP duality?
Do ESTp's generally get put off by deeply emotional touchy people? Perhaps the duality actually calms down this needy feeling that the INFp experiences?
