I have know this man since high school. After graduation we went our separate ways. After 23 years we run back into one another both single and we start dating about 15 months ago. We had very long detailed conversation about our expectation in the future. Our initial conversations covered, marriage, children both existing and future possibilities, careers, education, spirituality and family. After seven months we move into my house together and now eight months later he wants to continue to date but move back in a place of his own. Nothing drastic or even small has happened. He says that he needs his quiet time. So what do you think it really is?

Prior to you two moving in together what was his living situation? He may just miss having his own place...

Are you seeing any red flags such as: decreased affection or intimacy including sex, brief or short answers to your questions, decreased communication, or any other change in "normal" behavior?

If not, you probably don't have anything to worry about. He just might need his own space and quiet time.

Do you have any reason not to just take his word for it? That's a way for people to slow things down, as he may not have voiced it, but his feelings have changed and he no longer wants to see you everyday, and night. That would be my guess.

Sounds like he's pulling away slowly. Have you seen any signs like the ones Unlucky or Tal suggested?
