I'm going to try to keep this short and sweet. I was friends with a 33 yr old ISTJ for a few months, and then we dated for a month. He's a civil engineer and high-ranking navy officer. He broke up with me at the end of September because we didn't have a "spark", but he insisted that we remain friends. I felt blindsided by this because literally nothing significant happened, and he seemed very passionate about me when we first started dating. I met his family and friends, and he asked me about my wedding preferences (location, dress...). He wanted to take me with him to Romania, because that is where he is being deployed at the end of the summer. When it ended, I cried for 2 days and then mulled over it in my mind incessantly because quite frankly "spark" is a bs answer. I suspect it had something to do with me telling him that I was waiting for marriage to have sex. I try to make this known at the first date, but perhaps I wasn't clear. When I met him, it seemed like we wanted the same things (marriage, family, etc.). I guess I have a difficult time wrapping my mind around the fact that that in itself could be a deal breaker. Sometimes I wonder if he regrets his decision because he seems to get jealous when another man flirts with me or merely looks at me, he tried to make me jealous by going out with someone I thought was my friend and announcing it to all our mutual friends, and even now he occasionally brings up sweet memories of us when we were dating. However, because of his immaturity and his pride, I would be very surprised if he ever asked to get back together. There was also a time I blacked out from drinking too much on Halloween, and he held me (there's a terrible photo of it all haha). I really should stop thinking about all this at this point...I guess I feel that he lied to me and that he isn't as deep of a person as I thought initially since it was a lack of intimacy after only a month of dating that caused him to lose interest, and that bothers me. It seems that our relationship meant more to me than it did to him, but he led me to believe otherwise. Clearly, I fell too fast. Are ISTJ's manipulative? I am aware that many men see sex as a requirement in a relationship, but is that true for traditional ISTJ men who truly want to get married? I respect myself, and I thought such a man would appreciate that. There's more to me than what's between my legs.
