Are ENTJ and INTJ generally considered good mate's. He is a good guy really. just wrong time wrong place type of sh*t
Well I made differing experiences with INTJs. I got a friend in school, who I formed a dream team with. We both became the classes entertainers, picking on all sorts of funny things. But when school was finished tho, we never saw each other again.
Another INTJ I founded a little company with during school time. We sold websites, when the demand was high and made some money.
The last INTJ I knew, tried to constantly patronize me, I worked together with him as a student of engineering. He was quite some pain in the ass, cause he always wanted ways to be done he thinks is right and I just did it to get the internship done and say adieu then.
With girls its a complete different thing tho. I had two long lasting friendships with 2 INTJ girls (they were I think after all) and I got to know in the end that one of them always had a crush on me, but we never got past the friendship thing. She was like always a very logical person and I never got any signals from her that she wants more than a friendship, so I stayed in friendship mode. Its a long time ago tho now, but it was great. One of the two taught me how to play chess and the other one I learnt endless things about astronomy from. The on girl is studieing in Spain now sadly, living another life and the other has gone a way that differs from mine. She always wanted to study physics but instead became the life of the party, regulary visiting solariums, having all kinds of weird boyfriends. Its kinda really sad..
