I have a number of INTJ friends IRL and dated one.
There's feeling there, but it's under layers, tho thankfully not as many layers as for INTPs (we just come across as emotional b/c of the Ne, I think). My observation is that INTJs "warm up" over time and with people they're close to and trust. The display of affection might be non-traditional and unexpected, too, given the dominant Ni.
Te always seems to make Te-preferring folks hard-edged (and I do mean all of them: ISTJ, INTJ, ESTJ, ENTJ).
Mom will just have to patient.
Man, what a raw deal being compared to an INFP for apparent depth of feeling! You need wubbies!
