Did I push her to an emotional breaking point?

My girlfriend and I have had a shaky relationship. We’ve been on and off for two years. I’ve lied, cheated and unfortunately have even gotten physically violent with her. I’m not proud of the things I’ve done and the way I treated and misused her. I was fortunate enough for her to forgive me each time I messed up but this time it’s like she forgave me. Made it seem as though she was trying to put the past hurt behind her and that we were fine. She made me think we were gonna work on making us better and now all of a sudden she is no longer responding to my messages or calls. She deactivated her Facebook/messenger. I do remember a week or two ago of her mentioning to me how she holds a lot of her hurt and pain in (mostly what I caused her). She doesn’t speak on it or talk about it and that she tries to push through and have hope in me and our relationship but after her sudden disappearance, I’m thinking she reached a breaking point with me. I really hope she hasn’t given up on me.
