How do I cope and will she come back?

[lion575]

My girlfriend and I have been together for 2 years. I live in Manila (Philippines), and she comes from a very poor family - and I am quite wealthy. I know she was so in love with me and I took advantage of that and took her for granted. I support her whole family so ... I kind of was able to do what ever I wanted. I cheated on her numerous times with actresses, models, prostitutes ... you name it (but I can honestly say I never had feelings for any of those girls, I was just young, wealthy, and being selfish). I kind of came to the realization that she is really the only person in this world I care about, and I swore I would never do that stuff again. I started spending time with her again, then all of a sudden she said she needs her space and ran away. I found out their was another guy she had been seeing. She came back and broke up with him, and said she wanted to be with me and we would start over. Then a week later I caught her talking to the guy and was not angry but asked a lot of questions ... maybe smothered her. She then said she wanted to leave me. Then she said she did not want to leave me but just needed to go away for a couple months and be by herself and forget everything that happened. This all occurred the morning of our 2 year anniversary. She said she was leaving the next day but wanted to spend the day with me first. We made love (she didnt want to use any protection because she said she wanted me to make her pregnant), then she got my name tatooed on her back later that day, then she promised she would come back for me ... and then she left. She was also very upset with her family, she is still texting me but will not even talk to them. The other guy is not with her (I know that for a fact - Ive seen him here and he is coming y my place looking for her). I talked to her sister who she confides in ... and her sister said she was mad I did not propose when she came back, so I called her and said I wanted to come see her just to ask her one question and give her something ... she picked up on what I meant, and responded that she had wanted me to think of that last week before she left, now she just wants her space. Any Suggestions on how to keep myself sane, what i need to do, etc... . I really do love her so much and want to be with her (I know I am wrong for what I did before and trust me I hate myself for it - but what should I do now?).
