Hello, I am sorry you are going through this. It is completely normal to sometimes feel that we are the main cause of a break-up. Truth be told that is not what is important at the moment. Both you and your partner are going to hold some responsibility in the break-up. I am sure neither of you is perfect. Obviously, something was not right in the relationship which caused the split, but you should not feel guilty about that. There are always going to be problems in a relationship and staying in a healthy relationship requires work on both parts. Communicating your problems, issues and concerns are what keeps the relationship growing and going strong. If you feel that you played a bigger part in the reasoning behind the breakup, try to figure out why and try to work on that part of yourself. Sometimes these situations can help us to grow and learn more about ourselves. Do not beat yourself up about this breakup. We live and we learn, this is the truth, Good luck to you.
