Relationship Break

My girlfriend and I had been dating for a year when last Aug, she said she needed to take a break. She told me that she had made many relationship errors in her life and that she had been thinking about that lately. She has been married four times and has always ended one relationship and gone right into another one the next day. Her normal thing to do is already have the next one established when she leaves the current one. The reason I know all this is because she explained it to me and was part of why she needed to take a break, so she could heal herself from all the past mistakes. She also told me she was beginning to resent me because she was compounding everyone else's mistakes on me and making me pay for them. So as she is telling me she needs this break she tells me the we are still dating, still a couple, and she asks that I not see anyone else during this time since I still have a girlfriend. So reluctantly I agree to take this break. Here is where my question comes in. After we agree to take this break it was two months (Nov 1) before she moved out of our house. Then when she did move out she left some furniture and other things that she told me were some of her most prized possesions. She also left bathroom over night stuff, so according to her she will have them here when she spends the night. She also told me that this break will help her become a better person, us a better, stronger couple and in the long run will allow us to spend the rest of our lives together, and without this break we will be just break up. So as she is moving out I ask for her key and garage door opener back, and her daughters key back. She tells me that since she is still my girlfriend she is entitled to keep them. That way when she comes over she can get in, and this way she can also make surprise visits to see if she catches me with someone else. When I asked for my key to her apartment I was told " sorry you don't get one". Yes I have since changed the locks. Ok, she moves out and then starts calling me asking me to come over for this and that, and calls me every night before she goes to sleep. Then all the sudden she tells me I'm pushing to hard trying to see her and that I'm not allowing her to heal and miss me, and that if I don't give her some space she will realize that she did made the right choice by leaving and that she will be forced to break up with me which is something she claims she really doesn't want to do. So since the beginning of Dec we haven't talked much nor seen each other at all. I know for a fact she isn't dating because her family wants me back in the picture and they keep me up to date because they don't want me to give up on her. They tell me that everything she is doing right now is totally different than normal when is out of a relationship. Why did it take so long for her to move out after she told me that she needed a break, and why leave things behind? I look at it as by leaving them behind she always has a reason to contact me. So could she be on the up-and-up with all this, or do I just really need to cut my ties?
