I'm seeing a wonderful ISTJ man. He's always very kind to me.. always opens doors, cooks for me sometimes, and has only seemed to be irritated with me once in the 5 months we've been seeing eachother. We spend the majority of our time together. I stay at his place most nights, and he typically includes me in the majority of his social activities... but he just doesn't show much affection towards me. He doesn't seem too responsive either when I am being affectionate towards him. I mean, he doesn't push me away he just doesn't seem interested. He just seems distant... Also, he doesn't come onto me for sex. I'm always the one that has to initiate it. Is that normal for an ISTJ or should I see that as a red flag? If an ISTJ has feelings for someone else how do they express them?
