I still believe everything I said in my previous post (quoted above for convenience

). However, I'd like to add some things.
OP, you sound a lot like me. I am a planner; I like to know what is going to happen in my life. I like things to go according to my plan. I am not a spontaneous person at all. I am also a perfectionist.
Your boyfriend, from the very tiny bit of information you have posted, sounds similar to my Dh. Dh is spontaneous, not a perfectionist, is able to enjoy things as they come and not have a plan. He doesn't stress much about the future. Heck, my Dh's family doesn't even plan major holidays (Thanksgiving, Christmas, etc.), until a few days before hand! To say this drives me insane is a huge understatement!
A marriage between these two types of people can be extremely challenging. I would advise that you some how learn to address your need for a plan (and need for control, if you are anything like me) before you enter into a marriage. I know I drive my Dh crazy with always needing to know what is going on, and he drives me equally crazy with his "fly-by-the-seat-of-my-pants" lifestyle. We somehow make it work, and in a lot of ways we are a good "balance" to each other, but it can definitely be a challenge. Neither of us has been able to make any significant changes to our personalities in our 17 years of marriage, so just know going in that the guy you are marrying is going to be the SAME GUY 5, 10, 15+ years from now. Make sure you can live with his personality style!!
I do think your boyfriend has something planned. Drop the subject completely and let the guy execute his plan! If he says it will be worth the wait, believe him!
