In no order of chronology they've been ISTP, ISTP, ISTP, ISTP, ENTJ, ESFP, ????. Last person I don't know but I think they favored Fi-Te in some order. I've been/am friends with INFP, ENFP, ISTP?, likely ESFJ (ended horribly), ESFJ (also ended horribly but not nearly as horribly) ISTJ, INTJ, INTJ, INTJ, INTJ, INTJ, more INTJ?, INFJ, ESTP, ESFP, ESFP zzzzz. Probably more here, but my memory's getting short-fused. The best friendship I had was with the ESFP until she went kind of nuts (was suffering from a major depression among other things) and decided I wasn't a cool kid anymore and we should stop hang out.
In summary, ISTPs tend to like me a lot. I don't know why, as I am not nearly as fond of them as they are me, and I wish they could be a little bit more chasing by taking more initiative and keep up the intensity more. My longest and most successful relationship is with the ESFP, my current SO. She chased me long and hard though, LOL.
The two types I probably like the most are ESFP and INFP. ISFP have too high standards, I never seem to be able to impress them though more mature ones are cool (appreciate Ni more) and I seem to be invariably drawn to ESFPs wherever I come across them (a lot of my favorite fictive characters are ESFPs, even before I knew that they were). INFPs make good friends but they lack the decisiveness that I appreciate but I don't feel that they satisfy me nearly as much as ESFPs do. I think second to this, I would probably say INFJ. ESTP is kind of ok, but is so hit and miss I wouldn't bother with it most of the time. There's too much Fi-Fe clashing.
I never understood the INTJ-ENFP thing, personally... It's like people think this pairing is the second coming of Christ. The only other couple pairing that stands close to it in typology circles is the 4-8 pairing which I don't get either because the first ESFJ that I knew and was friends with was likely a 4 and she began to introject hard on me and when I realized I got so repulsed I ditched her. The other ESFJ was also a 4 and I couldn't stand how I felt I kept cultivating our friendship and I thought it meant something more than it apparently ever did; I felt betrayed and I ditched it. One of the INFPs I know is a 4, but we drifted apart and the ENFP 4 I know is driving me insane with his lack of Te logic and I feel like I have to become a Te dom around him and I don't even favor Te as a cognitive tool that much. So yeah, fuck 4s.
