That is fine for me because I don't mind making it clear that I won't decline an invitation when I'm interested. I like to make it easy for someone when I'm into them. Him planning the next date suits his type, and me getting surprised with the specifics suits mine! He's getting back to me on it and I don't mind having another reason for us to talk ^_^
He is sort of acting like I am a girlfriend already. Not with the physical stuff, and I don't know if I can articulate specifically what I mean. I just get that vibe from him, I don't feel related to like someone he can potentially see himself with. I feel related to like someone he sees himself with already. I guess that means he isn't seeing other people (???), or your type does that with anyone even if they are seeing more than one person at the time.
It would probably be a good idea to stay quiet about the fact that I lost interest in "dating" since we met. For now anyway. Right? Yeah. But then maybe stuff like that doesn't freak out the ISTJ? (I am waffling because I kinda do want him to know that.) I guess my plan is to play it by ear and if I feel like blurting it out I'll trust it's okay if I do. If you or another ISTJ think this is a terrible idea please let me know!
It's funny because I was totally digging him first, and then I discovered through research that Keirsey suggests our types together. I can see why. Works quite well, imo. Your type has the most incredible character.
