What to do

Okay here's the deal. I started dating a girl who is now 21, just turned 21 this September and I'm 23. We dated for a few months until we were official. We started out staying at each others place once or twice a week, and then three to four days a week and then everyday. She practically lived with me at my parents for a few months (she brought her clothes and things there) and she also had her own apartment she shared with her sister. I purchased a house in April and her and her sister moved in with me. Her sister stayed for 4 months until we told her she had go..she was messy and I didn't like sharing my home with her. Everything seemed great and I started playing the husband role and I work a normal job while my gf works as a server at a high class bar. We talked about kids and marriage but both wanted to wait till we were close to thirty. I co signed on a car for her and we got a dog together...making all the normal moves. About a month and a half ago she seemed a little distant and I always asked what was wrong etc...and j believe I gave her more attention and wanted more time w her than she did with me. I scheduled my work around her and other activities because of our work schedules we didn't see each other that much. So we had a talk and she was worried we rushed into things and she was stressed. She now has a high car payment high insurance and half of the bills for the house. So we had that talk and she ensured me we were good and everything. Well a week later she goes to a college to visit her friend who likes to down talk boyfriends. She acted fine but said we had to talk. When she got home Sunday we kissed she went to the bathroom and said let's talk. She then told me she didn't think she loves me like that anymore. I had done something romantic the week before and she said she didn't feel how she should etc. I told her let's try and take some time but I was very hurt and she could tell. We haven't talked to much since than but she did hook up with a guy she works with (no sex). I confronted her and she said she was drunk and upset and feels horrible and it's not she wanted. Since than ive said I'm not waiting on you its not your choice anymore and she wanted to talk and see me. I declined I didnt want to work on things when she wants any longer. That was a few days ago. She's been taking her things from the house and I took all of our pictures down and put them away. She went there and asked where they were and took them and our curtains in with out the hangers.... She left a picture on our bed and left a note that said I'm sorry, I love you and I miss you. We've texted a little throughout this and whenever I mention another woman I'm talking to she really responds. I also have told her I'll be fine no matter what. She texted me last night saying I miss you. And I said oh you're on my mind and she said I hope so. I never responded and then she got a hold of me this morning. She asked what I was doing tmr and wants to see me. I haven't accepted ive just ignored it almost responding to other things she's said or just joking around. She said well let me know she doesn't care what we do she just wants to see me. Ive been thinking about just telling her I want to take a month off with no contact. She knows i love her and want her back. She says she's been thinking of how good we are together and trying to figure everything out in her head. She's been stayingnwith her sister and friend. We had a great relationship and were really really in love. Ive never felt this way about a female before but she knows that already. She was always on board with us making a life together but Idk if she just got scared and stressed and thought maybe I was the problem...and this is all after turning 21. My question is what should I do from here, I do want her back.
