Liz,
I agree that you should take time before moving in with a man. You need to know him very well. What are his habits, ambitions, goals, views on a lot of subjects, his values etc. You have to find out that you are compatible with each other, that you'll get along most of the time and that you have chemistry together. Finding out these things about another person takes about 2 years.
Is he a good person? Does he have any criminal records? How many times has he been married? How old are his kids? What are his commitments ? Does he have a stable job and make enough money so you both will enjoy a certain kind of lifestyle?
Moving in with someone you don't really know well is a form of suicide, you could get hurt physically if he has a history of spousal abuse, alcoholism, drug abuse.
Please don't be in a hurry to do this. Enjoy your freedom, know him well, get to know his friends, relatives and co-workers. Don't be in such a hurry. That will come to that point. The decision to move in is between the 2 of you if you are both comfortable with each other.
Take care.
