What should I do my ex girlfriend is sending me mixed signals?

Well my ex girlfriend got in Trouble and she had to break up with me because of it, and she told me she still wanted me to call the time so I do, and she wants me to still tell her I love her, we broke up on a Friday about a week ago and the Sunday after she kissed me (Yes on the lips) and promised me that it wasn’t going to split us up but when ever I do call she is always busy (Usually out with friends) but the other day when I called and she said she was working and said she would call me later and that her phone signal was bad so I said ok Love you and all I heard her say was You too now I know I am prob over reacting but… my friends are telling me stuff like

1. I think she still loves you she’s just hiding it
2. I don’t think she is worth it she has tried breaking up with you how many times (because Her dad doesn’t like me for good reason because I don’t have a job) and these are prob my 2 best friends just one is short and to the point and the other is short and sweet and knows how it is to love somebody and then loose them, But my ex said she doesn’t want to loose me and I don’t want to loose her ether but it just seems like she doesn’t really care about me sometimes ( I have told her many times I hate crying about this but I do ) and I try not too but she always tells me to say what I am feeling and if I say never mind she gets mad that I don’t tell her and there have been a few times she has cryed from me telling her how I really feel like I told her ( I missed her ) and she started crying and I asked her not too because I Really Love Her with all of my heart and we had a good talk tonight she and I talked about my job problem a lot in the past and still do so I said why dont I join the army at first she didnt want me to then I said its the best way to get me on my feet and be able to take care of you then she started supporting it so I told her I wanted to tell my family first so I did and in the proses found out some more info but w/e the other day she told me to better myself and I agreed but was more or less trying to get her to tell me how she felt with out her really knowing ( Kinda worked but yeah didn’t ) she told me to better myself weather or not she was in my future or not but how she said it told me that she may of given me a hint because her dad doesn’t like me and wanted me to join the army in the first place so I think she is doing what her dad wants her to do being brought up by HER dad has thought her tough love and I have been told by a few friends to just move on and she isn’t worth it but my friends mom said ( once you love someone it doesn’t go away like that ) and my ex said she has been crying for the past 2 weeks about our break up but wasn’t showing me any emotion except when she would tell me she loves me and still does now I know I should really give her some space and get on my feet and I am working on that but I can’t help but hope we will get back together and I hate that I can’t stop thinking about her but I need to back off of her a little and get on my feet I most likely wont take the advice unless I find it help full and not like the obvious move on and forget about her ( Harder the you know ) but w/e the basics are we broke up she is sending me mixed signals or she is dropping hints or w/e and I need to get on my feet ( By joining the army in this case ) I guess the things I would like to know based on the info I have given is
3. Do you think me and my ex girlfriend will get back together
4. How long after signing up should I wait before I try and get her back ( if I can )
5. I guess any other help full info I can get
