Okay so. He's conflict-avoidant and generally doesn't make waves unless he's pushed, but can get very frustrated at times. Because of this, he never was really ambitious and had to be pushed into making more of himself, as it were. Amazing at getting to know people and making small talk because he has an ability to adopt their lingo and manner of speaking. Likes to try new things; traveling, cooking experiments, etc. Good with practical knowledge. A terrible liar. Can be gullible and buys into things like alternative medicine and is open to conspiracy theories.
He and I get along in the sense that our humors are compatible and bounce off each other, but he likes to push my buttons and say things that are blatantly incorrect to make my Ti frustrated to troll me.
My mother is an ILI and they get along well. She's stuffier and has a terrible time relating to others, so he smooths things over in that regard. They're not just comfortable with each other, but still very much romantically involved after a couple of decades of being married.
If I think of anything else, I'll post more, but here we go with the pictures! If you have any questions, also, feel free to ask.
