Relationships

What should I do about my ex girlfriend, I was the one who wanted to break up, but I still miss her after half a year?

We were in a relationship for 2 years. Lately she was very angry and yelling for minor issues, like some accidents with food, clothes, . she never was happy. One day we were at my place and there wasn't any bread for dinner and she was hungry. She was yelling so bad and hitting things in the appartment. It is true that it is my place but still after 2 years, she also could think of it. So i ordered a pizza for her. She was yelling that now its too late,... then she opened a pizza, and destroyed it with her hands, like its garbage. Then she ate few pieces and went to sleep. Let me mention: we never cheated on eachother, we spent time together, went to different places, i always came to take her to different city, because she didn't have a car, i payed for everything, because she couldnt afford this things. We never had problems with sex, she liked it a lot actually. I wasn't perfect either, especially at the beginning i was working a bit too much and we didn't have so much time together, but last one year, we were together for every weekend and really enjoyed. This time i really had to break up. I was thinking that this actions express that she wants to leave and she doesn't want to tell. She didn't even try to prevent , after i said its over she accepted and never messaged me again. I expected her to call or message and appologize for that bad behavior. I would accept it, because i still care for her. Now 4 months passed. Still nothing from her. I thought it would be easy to move on, but i realized i really really loved her. I downloaded tinder one month ago, because i thought maybe i should forget her and start something new. But i dont want that. I didn't even invite any girl out, i still think about her every day. But if i contact her now? I love her still, but i dont want to see that anger again. Do you think that can even change or she is just like that. How should i tell her that i still love her, but on the other hand that i can't take that behavior anymore?
