How should I go about this break-up?

Ok so about a month ago my gf wanted a break with me. I realized what I ve done wrong and my insecurities got to me, but I loved her like no other, she was so pure to me, precious, sweet, innocent, cute, list goes on.

Now we got to a point were I gave her some time and had little talks here and there but it was never a fight, only just seeing how we re doing and talking about us. But I ve been working on myself a lot, and I mean doing a lot better than I was and I wanted another chance. I think I might get it, but might have to wait until after graduation (around another month).

The thing is I don t know what will happen in that time, at the moment (through social media) it seems like she s having confrontations with this guy. They hung out when her parents were on vacation a week since our break and she lied and said she "went to bed" but found out he was over, she said she didn t want to hurt my feelings which I just tried to be positive. But now I see him saying stuff on social media like "I hate seeing people move on but maybe its for the best" blah blah blah (although her sister was in a breakup same time as us, and he liked her before). But we talked a little sunday/monday and she changed her status to hidden instead of in a relationship with me and changed her profile pic also... I ve taken it as in we are done, but she said nothing has changed and time is best for us right now, considering I said I wouldn t be home until graduation. I just don t know what to think..
