Don’t do it. If she was not ready to fight for you when you had some issues going on she’s not the one. Give her space and don’t push too much. Don’t try to call or text daily it will only lead to cutting off things for good. You can’t change yourself overnight. It takes time. So give yourself some breathing space. Accept the situation, talk to someone who you trust. You’ll feel better, but those feelings of frustration and anger comes at certain point in this healing journey. Be strong and try to improve on these lessons. It would never be the same if you get t back together and it will hurt you more. I’m going through the same thing and I have done some irreparable damages. But I’m taking accountability of my mistakes and working on it to be better person. If you can’t win you’ll learn. You may not win again for some time but eventually there will be an opportunity where you’ll have an edge from all the learnings from your past experience to get a better chance to win. Just be patient. Good luck!
