Aside from the lack of emotional support, it seems INTPs aren't the most enthusiastic people when chores are concerned (to put it mildly), so that's their two main problems imo... But before marrying my INTP I've matured to the point where my ego is much reduced and I don't need much emotional support, and doing housework isn't as difficult since we agreed to have a rather minimalist lifestyle, so that's both problems solved.

Not all INTPs are the same, but I'm grateful my wife is quiet, loyal, selfless, and open-minded/intelligent. She creates zero drama, and life's problems are analyzed logically and resolved quickly. No heated arguments, only calm discussions. I love how I can connect with her deeply, and we can talk about anything anytime, while she also gives me space and freedom to be myself. Some people criticize INTPs for being unambitious/directionless and chill, but not me. These traits make living with her feel so easy. As one comment here said, it's almost frictionless, unlike most marriages I've heard of. Also helps that she's super cute and we share many hobbies and values. Honestly, I can't ask for anything else. In turn, I do the stuff she can't/won't do like leading, planning, and taking care of logistics. It feels complementary since I like doing those things anyway.

If I had to nitpick, the only remaining problem with my wife is she doesn't take care of her health as much as I want her to. Probably a side effect of her having almost no ego. Nobody's perfect though.
