If I Give My Girlfriend Space and Not Contact Her, Will She Come Back Around?

We've been with each other for about 8 months. maybe 2 or 3weeks ago, we went on a break because we got into a big fight. We were together but she wanted to take a break so that she can get her job together and grow as an individual and when we get back, she could be a better girlfriend to me because she said i deserve it. and because we're planning on moving in with each other. But Everyday we talked and it was my fault we did because i was scared, and every time we talked she just said, "babe you need to trust me, i need you to do this for me". a week later we ran into each other at village inn, i asked her to come over and we talked and got back with each other. When we got back with each other i was really emotional (lol) I wasn't over that pain i was feeling that we had to take a break, and it was bothering her. well a few days ago we kinda got into it. and she wanted to take a break again. She said she wants me to get my emotions in check because it was becoming too much for her and what not. But just like the other break, agreement is. we're not talking or looking for another relationship, we still love each other, she just feels a lil smothered. She even told me she was close to saying, she was done with me completely because i would always find a way to have a talk to her and basically beg saying, "babe just do this for me and what not". Well Today I didnt contact her at all. My female cousin is friends with her so they are cool and when i was with my cousin, my girlfriend called me and asked if i could take her to the bank, so i did and we all had a talk in the car basically stating she really wants me to take this time to get my emotions in order. she's not moving on, she just wants to be alone for right now. etc. And of course i believe her, because its a possibility she could be pregnant also. So i plan on not contacting her for a while. maybe 2 weeks or so?? idk.. and before anyone says anything, i know that there isn't anyone else because she works basically 7days a week, 9-5 and know that's a big stresser on her as well. Could anybody give me some advice. Good advice on getting her back and staying strong etc.??? How long do you think i should give her before i converse with her, ask her to spend time with me etc.??
