NT's have feelings, and often much stronger, more primal emotions than feelers.
The issue is that feelers tend to place higher priority and value upon their feelings, while NT's are less likely by far to understand them or try to use them, leaving them either pretending they aren't there, or unrefined.
In my own terms, the question "how do yeu feel" is not quite irrelevant, but it usually leaves me a bit stumped, I may have strong feelings on the matter, but not be sure how to express them, or explain them, which can just lead to trying to say "I don't know" or "Let me think about that", both of which are usually interpreted as not having any, when it's moreso just not being sure how to express such, or not caring that they exist.
In terms of love, I've found it's actually much less intense of an emotion than people give it credit for. They're always like zomg love is teh strongestestest emotion evah!
...Not really, that's lust.
Love, in my experience, is something that would actually make me do alot more for the person I care for than I would normally even consider; act in ways I wouldn't dream of normally. The one I care about currently, I would be totally content to just rest my head on his lap and nuzzle against him, which's a bizzare concept to me.
I suppose it's more like a more significant, and deeper attraction than just a friendship, but it's still truly based on friendship. Most of the same things yeu'd do with a best friend, I'd do with my SO. Play games, talk, be silly, etc etc. The idea is just that, once it goes into love, it's more than 'just friends', and sex isn't a requirement there either. Moreso it can lead to actual affection, and at times, a sense of paranoia at times. If they break their standard habits, like say... if I'm used to them always logging on AIM while they're at work, and they don't do that one day... I tend to panic, for fear they're injured or something.
I dunno though, they cover everything from being my emotional support, to someone to toss my weird theories or ideas at, to someone to play with and have fun, but essentially, the one person who does everything I would need to be content and happy, all rolled into one, who I could just cling to forever. Until I saw something shiny.
In any case, the feeling of love, that I've felt, is one that's very deep but it's more like a calm serenity (or wildly silly at times of course XD ) rather than intensity. I've found the intensity to just turn out to be lust every time. True love, I just can't imagine myself without them anymore, and get that rush of thrill just seeing them is like a sudden burst of YAY!
However... there's also the matter that, unlike most peoples... I have no lasting loyalty either. Yeu see the average person, even if their parents or siblings or SO or whotever does horrible things to them, they endure it because they're "family", as if it has some special connection. It means I'll tollerate them slightly longer but... respect and loyalty are short term goods; they expire quickly for me. Yeu continuously earn such, and maintain such. As long as yeu provide reason to provide these things, they are maintained; if yeu regularly show a lack of value to be respected or cared for, I will just drop yeu eventually, regardless of our relation.
I'm not likely to stay in an abusive relationship, nor likely to tollerate someone consistently being suck. Hence, love probably isn't forever for me, but never know, that depends on my values changing at the same rate theirs do and in the same direction.
