Thank you for sharing this. This is valuable insight. I have talked to them both about serious issues and sometimes I have received what I perceived as a "don't worry, be happy" kind of reply. I didn't know that it was a way of putting energy into whatever may be positive in the situation or encouraging someone else to do so.

Yes, definitely. It's just like The White House, actually - all of the most serious work happens away from the public eye, and everyone else has to rely on the press secretary for information. And while the press secretary's information may be accurate, it completely leaves out the deliberative process.
How appropriate of me, comparing ESTJs to the government.

Pardon me for enforcing stereotypes!
This probably also tells me that with one of them, this is what came out of 'being in his head'. That sucks.
Well, actually, the "being in his head" part was the part that sucked. In my case - and maybe in your ESTJ's case too - the cheer shown when telling people that is usually entirely genuine. Because the reassuring words they're saying were likely used before that to reassure themselves, too.
I hate this kind of thing, too. I've gotten to the point where I call it out if I see it happening. Well, at least the emotional manipulation.

I need to get better at dealing with that. The last time someone acted like that towards me, my pissed-off-o-meter went from zero to sixty in less than a second. I couldn't hold it in at all - I just went "God, don't talk like that to me. Just tell me what you really think. I can take it."
People don't think of me as aggressive, but that's because I avoid any conflict that I deem to be 1. overly risky, and/or 2. unnecessary. (I'm 99% sure this comes from my enneagram - and maybe(?not sure about this self-typing) having self-pres as #1 on my instinctual stacking.) But when it's necessary, or when there's no risk, or if I'm mad enough that I can't hold it in anymore, THEN you'll see EJCC acting aggressive - as in the above example.
It's not a good thing and I'll never understand it. How the hell are you supposed to know where you truly stand with someone? One of my favorite quotes is from an INTJ I know "I take my truth neat." If you can't be real, it might be better to be quiet. Gah--I better stop...my blood is beginning to boil. I need to move back into my cool INTP zone.
I am as well...maybe even more so because I was just in (and still extricating myself from) this same situation. Just reverse the genders and that's me and the ex.
Hope with caution. If you find yourself paired with an extroverted feeler, it's going to be some rough going. Guys are less likely to do it but they do exist (my ex is ESFJ) and well... It can work if you're dealing with someone mature (I'm already working under the assumption that you are) because it creates openings for communication despite personality traits, beliefs, and attitudes.
Not only that, most, if not all, people have expectations. In all the relationships I have been in, I've only been with one person that wasn't thrown off by being what most people think of as "masculine" (emotions, how I deal with problems, how I think, etc.). People have constructs in their heads and when it doesn't match with reality, either they will adjust or they will cling to the construct and begin to find fault with reality. Whoever you end up with, I hope they see and value you for the gifts you bring to the relationship and are willing to accept you as is.

I hope so too. And I know what you mean about Fe and maturity. The situation I mentioned earlier, with someone being really passive-aggressive, was with an immature INFJ guy. But one of my best friends is an ENFJ, and he's very mature and honest and smart, and uses his Fe more for the purposes of tact than for sending mixed messages. (Too bad he's gay.

)
Not in real life- I think that my weirdness and the parts of me that are not as much Stricty ESTJ are more of a disadvantage in Real Life. We ESTJs function pretty well in the real (organized, punctual, dependable, rational, thought-based) world, and I feel at home in the world most of the time, unlike my INFP friend, who has said that she often feels like she doesn't belong.

I do feel like there's a lot of ESTJ hate, as well as a lot of S-hate in general, on the forums, but there's not as much as it used to be, and it bothers me less than it used to. If people are going to be prejudiced against me based on a caricature of my personality and not get to know me as a person, that's their loss and their problem.

Yes.
For sure! ENTJs ARE evil bastards, FPs have their heads in the clouds and couldn't form a rational argument to save their lives and are probably crying right now, etc.
Definitely.

The ENTJs are evil bastards trying to take over the world, the INTJs are leading the ENTJ's secret police and torturing people for information in some unknown, protected location... and while the xNFPs are crying about it, the INFJs have gathered together, tied themselves to a tree, and started singing "Give Peace A Chance".
The xSTJs witness these crazy antics, and they sigh, shake their heads

and get back to editing Excel sheets in their corporate cubicle jobs.
i have had a very similar situation recently, and felt a very similar way. embarrassed and displeased - and came up with a similar solution of telling people i was just getting used to things and planned to pick up more activities later. it's comforting to hear of someone in a similar situation

Aww. I empathize. Has it worked out okay? It's worked out for me, so far, this semester. I've found two or three clubs to try out - although I really wish I had an opportunity to play percussion again.

I'll keep looking, for that one.
