Should I get another chance?

I was dating this woman for 3 years when we met she was still married she separated from her husband of 22yrs a year later finalized the divorce (allegedly) everything was good between us except she was always keeping tabs on her ex where he was where he was going who he was with those kinds of things as well as textn and calling him behind my back and saying that she wasn't talkn to him. On Jan 8th she went through my phone while i was asleep and found a text conversation i had with another random girl and so she broke up with me and subsequently ran back to her ex. Now she won't even talk to me. Is she in the right or should i get another chance to make things right?
