I'm also an INFP. Not exactly suitable but I think it'd work.
There will be a lot of good things but there'll be few major problems. Both will be pessimistic. No motivation. Lost in our heads...
I get along well with extrovert people. Most of best friends are extroverts.

Nope. A number of things jumped out at me: can be pessimistic, can feel victimized, prone to crying/sadness, emotionally moody---that sounds like a mess.
I'm assuming that isn't you though.
