I have hidden the truth/lied to the love of my life for 2.5 years. Can this be salvaged?

Wow..I'm a little confused but I think I got it. Whatever you did before being with her shouldn't even be an issue..if we all had to answer for the things we did before meeting out SO we would all for short. When you broke up you had every right to move on just as she did..that should not be an issue either...except maybe for you and the fact she ran back to her ex so quickly ( red flag ) This woman has serious trust and insecurity issues.I can tell you are a great guy and want to work this out, but she has to be able to take responsibility for her part in all of this. I don't think you can " fix " things by constantly apologizing for things you don't need to apologize for. You haven't cheated on her...she is playing this out like you have and you are giving in to her drama. I think you need to take a step back and let her try and see her part in all of this. Let her apologize to you for a change for her on again off again love for you....one night she loves you and in the morning she doesn't WTF is that about??? I understand you wanting to work this out and the fact that you love her..but frankly I think she might need to talk to a professional about her issues she has with trust and relationships in general..otherwise you might be on that roller coaster for a very long time. Good luck :)
