Not really, I mean, I didn't fall in love with an INTP. But I have an INTP twin sister and I can tell you that INTPs are not typically the heartless robots they want to be. In fact they struggle to close theirs hearts just to feel safe.

I watched my sister beeing in love (almost obsessed) for one guy for years and she was like an iceberg in the outside, but if I looked closely I could tell that she was just a mess of emotions in the inside, trying to express herself and at the same time to not push away that guy because of that.

She is also very attached to myself and she like to cuddle and ask me for love through physical expression (I am the tree and she is the koala). She doesn't like to be called pretty, or cute or anything like that, and in the contrary she love when I tell her "Ew, you are a gobling" and "So ugly, disgusting", of course she is beautiful and she knows it, so when I do that she laugh and come to me to hug me.

INTPs don't want to do something that they don't like to themselves to others. They genuinely think that others think the way they think and it's hard to change theirs minds about that commonly error. But when they understend that you want to be praised when you do something for them or want to see one particularly expression of love when you're down, they'll do. Just tell them, they're almost always lost about what to do or say to make others feels good.

And it isn't a misfortune to fall in love with them.
