Well, she's actually a woman.. Just wanted to get some points of view on this...
There's an ISFP I really just adore who has a long distance boyfriend, and their relationship is on the rocks. You could say that I have a crush on her, and she knows it and also I know she enjoys my company. The crush itself is amazing, very dreamy, magical, almost platonic feeling.. almost. I find myself just wanting to be around her, just to be around her.
Getting to know her has been a very slow process. The only reason I was able to get in her good graces in the first place was because I met her when she was drunk, a rare incident, and we had some deep conversation. And I subletted a room at her place for a couple of weeks, and was able to show her I'm a sensitive, reliable dude (Yes, an ENFP who's reliable), which she values, and I was there to help out when she got sick. If that hadn't happened, I wouldn't have ever caught up with her.. she never stays still enough to really get to know.
So, lately it's been pretty touch and go. She'll invite my places and then the plans will be canceled, I show up randomly, she looks put out, but warms up at the end and says she hopes to see me again, only to be put out again when I show up. The last time I hung out with her, I kinda just showed up at my good friend's house where the ISFP was crashing, because I legitimately needed a getaway for the day, and I didn't mind having an excuse to hang out with her. She bolted for most of that day, I'm sure she thought it was very rude of me (and said so in coded language), but by the end of the night we were watching TV on the couch with her leg up on me.
So, I know ISFPs are supposed to be a little flighty, but I'm going to assume that maybe she is more so because of the boyfriend. Also, I know she is just flighty with guys in general, having bad past relationship experiences. This is why she has an LD relationship, she has said so herself. I feel like I'm getting to the point where I might be end up being obnoxiously intrusive.
So, I *think* I'm going to back off, and only come hang in incidental group settings. But, do ISFPs ever get to the point where they take the initiative to show they actually want to spend time with someone they like and actually show up? Or will it always have to me trying to pounce or nonchalantly floating in at just the right moment in time?
