My INTP pretty nearly stalked me. It took me awhile to catch on. He just always seemed to be wherever I was right before I went to dinner. Then he walked me to the cafeteria and we ate together and hung out until he had to go to work or the dorm curfew (we were at Bible college), whichever came first. I'd already kind of decided I was marrying him, so it was okay. I'd more or less decided it by the end of our first conversation.
The only ambiguity we ever had was when, early on, he sent me this card that said "friends" on it about a billion times. I freaked out at first, thinking he didn't like me romantically. Then I talked to some people that knew him and they told me he was probably trying not to scare me off. (I guess his courtship style had scared girls off before. Stalking. Big surprise.) I decided I would want to be his friend even if he was a woman (not my preferred gender), so it wasn't unethical for me to continue to be his friend even though my interest was not strictly platonic. He did not act as though his interest was platonic either, so I just waited to see.
He proposed sooner than I expected or thought was prudent, but engagements aren't binding and I knew it was against school rules to get married during the school year, so I went with it.
I did watch for deal-breakers during our engagement. I didn't want to end up getting divorced. There were two times when he was on the cusp, so to speak. Both times I was satisfied with his choices.
I know it sounds stupid to say I just knew, almost immediately. I thought it was stupid at the time, but the feeling was very strong. It's still very strong and it really never should have worked. We were too young. We were too poor. We had kids too soon. We had too many kids. Two of our kids are 'special needs.' But I like him. I trust him. I respect him. I want him. And he doesn't try to hide from me. He actively seeks me out, not all the time. A guy has to keep up with current events and play WoW, after all, but he likes making me laugh. He likes telling me about articles he thinks I'd be interested in reading. I still have to keep telling him not to grope me in front of the kids. For an INTP, I'm pretty sure that means he likes me.
I never saw the sense in leading someone on if I was pretty sure I wasn't interested in them. I did not play hard to get or anything like that when I felt it was right. I didn't chase, but I didn't run away. I didn't share my every thought, but I didn't mislead. The only 'obstacles' I put up was simply observing as objectively as I could despite my feelings of infatuation and lust, to determine whether or not I thought it was going to work long term. I almost always try to keep the long term future in mind. It's my nature to do so. Otherwise, I was pretty much all up on him.
Not saying it's like that for all INFJs. No idea how it looked to anyone else or how many guys may have thought that we had potential. Probably not very many because I've never been what most people would call hot or anything like that. But that's how it was for me.
