Sorry, we ISTJs just don't do compliments.
When Fs are facing a problem, they seek support. Not necessarily to have a direct answer, but rather to understand the situation where they are at. They'd like to make sure, that their decision is supported and accepted by other people. They'd like to know what other people would do in their situation and if their decision is just for other people. When facing a problem, Fs are primarily looking for acceptance and support.
When Ts are facing a problem, they seek answers. They see a problem, and seek direct answer to it. They are not looking for sympathy or acceptance, but usable and valuable information to help them to make the right decision, based on facts they've gathered. So, when facing a problem, Ts are primarily looking for answers and solutions.
That creates an interesting setup in problem solving between T and F. Reminds me of a dialog between man and his wife in this movie called "White men can't jump". I think this something like this:
Gloria: "I'm thirsty.."
Billy: "I'll go get you some water.."
Gloria: "Whattefuck?! If I'm thirsty, I don't want you to bring me a glass of water, I want you to say, 'Gloria, I too know what it means to be thirsty.'"
...but now we are quite a far from the marriage point... so let's get back at it. I read a study saying that men don't marry the women they are most in love with. They choose women they love, but are not overwhelmed by... to retain control. Men are generally T-like, so one could draw a conclusion here that love isn't the number one reason why T-people get married. It's something else... maybe they are looking forward to see their needs... what kind of father/mother they would like to have for their kids... what kind of person would they like to have at home, after a long and stressful day at work... I don't know.
But I haven't felt love strongly ever. I feel more of a fulfillment and harmony. So, as of now, should I get married, I'd be marrying for harmony and fulfillment... not for love.
