I kinda miss my ex but I don't want to get back with her

I was in a relationship for two years We understood each other and everything was normal in the first year Then we started to grow up and our thinking changed We each had our own thoughts and paths to the point that our relationship became distant after we used to be together every day So things changed At first I was the one who caused the conflicts and we would sometimes end the relationship for days sometimes a month or two but in all cases we would get back together Both my family and her family knew that we were in a relationship and were very accepting Anyway one day about two months ago she told me for no reason that I hadn't done anything for her and that she was only staying with me because she loved me and that I was always putting her down When I told her that I had done this and that and the other thing she said So you did all that just because of She kept talking to me about him telling me what I did even though she was the one who told me to tell her what I did for her Her words were unconvincing and very confused and when I said she didn't deserve all this she told me we were finished and we haven't spoken since I'm thinking of sending her a message to at least understand the reason behind her actions, but at the same time I don't want to go back to her at all I need a solution.

And you see I don't regret the relationship or the time spent together on the contrary it was true love and we were both very happy But in the last few months the situation changed
