Move in or not?

Please pardon the personal questions, but his and your backgrounds are needed to get the full picture:

I see no indication in your writing that shows where he asked you to move in. Has he told you how much he loves you and vice versa? Do either of you have children or dependents? Are both of you able to support yourselves financially without one of you moving in? Do you work full time? Is he over his last long-term relationship of 8 yrs?

If I were you (based on such little info), I'd Stay put for now.

He has not asked me to move in, neither of us have children or dependants. We are supporting our selves. We both work full tim. He tells me often he loves me. He says he is over his longterm relationship.

show-stopper: He has not asked you to move in? Then there's nothing to consider seeing that a move like that is speculation on your part. And he feels pressure when the subject of marriage is brought up. Enjoy your time together. You are more of a nester (not unusual) at this point.

Furthermore, why is he not visiting you at your place? Why is it always at his place?

Yeah, I think it would be good to get a better understanding of who you guys are as people. How old are you? Where are you living now, where is he living? I feel that if you force yourself to move in, it will not end well, in the sense that he probably didn't want you to move in in the first place, then he will resent you cuz he does not have his space, then he will treat you crappy, and cheat on you or break up with you. In the mean time you invested a lot of time and emotion into something that probably was never going anywhere because he didn't want it to from the beginning but never told you because he didn't want to hurt you and it probably feels good to have a girlfriend he can do "stuff" with.

Not always is that true - not that he intends to be deceptive. Not always is there an awareness of what is over emotionally until some considerable time has passed.

Patience, grasshopper.
