There was actually a kinda similar thread a while back about how do you make an ISFP fall in love.
I answered it thusly:
"Making me fall in love really only takes two things:
1. Give me lots of attention
2. Be awesome.
One way of doing #2 is by doing #1. Other ways include giggling a lot, talking cute, twirling your hair, banging your head to the music, putting your bare feet up on the dash, singing happy songs, being goofy, putting your head on my shoulder, smelling nice, suggesting goofy activities, wearing tight colorful clothes, looking at me with wide eyes, complimenting my musical knowledge and overall awesomeness, giving me random little gifts (especially ones you made like made out of paper with markers and colors and writing on it that says stuff like "Special Jeff"), drinking a large amount of soda and then either belching loudly or saying "ahhhhhh" in a very refreshing way, doing jumping jacks or various cheerleader routines, watching movies with me, eating buttery popcorn and licking the butter off your fingers, spinning around in a circle until you're dizzy and falling down, giving me a back/shoulder rub, cleaning my apartment, cooking good food for me, making me a yummy smoothie, saying random stuff, calling me goofy names you came up with, sucking the spaghetti up into your mouth, playing video games, talking like Simpsons characters, talking and playing with my son, cutting my son's hair, jumping on a trampoline, wearing camo, kicking and punching the air like you're doing martial arts, actually doing martial arts, catching the rain with your tongue, eating an ice cream cone upside down, valuing life, praying with me, listening to music with me, whispering in my ear, going to waterparks with me in your hot swimsuit, playing beach volleyball, coloring, surprising me, letting me surprise you, smiling, laughing, holding my hand, winking at me, making up funny words, talking in weird voices for extended periods of time, giving gifts to strangers, riding the shopping cart down the aisle (wheeeeeeeeeeee!), spontaneously declaring a thumb war, making me breakfast, calling me on the phone to ask questions about stuff i know or just to tell me you were thinking about me, skipping, saying something would be better with nougat, writing my name on a balloon and giving it to me, going to church with me, introducing me to people, kissing me in random places, kicking your shoes off, pointing out my sexiness, stopping to feed squirrels, playing songs on the jukebox, eating hot dogs, cheering for our sports teams or Morgan's teams, listening to the radio with me, working out with me (preferably in awesome tight workout outfit), spelling words with the letters in your alpha-bits, wearing your hair in different cute ways, gently head-butting me in the chest, enjoying monster truck shows, telling me what's on your mind, crying when it's time to, letting me cheer you up, watching the sunset with me, giving me that look that says you can see deep into my soul and hear every bit of the light and the darkness and the fear and the insanity and the spirit and you still want to be with me as much as ever.
So, yeah, it's not too difficult. There's so many ways, and so little time. Get busy.
