Things ended 2 years ago but I still think about my ex everyday

We only dated for 6 months but she broke things off with me after finding another woman she was more interested in (she thought I didn't know that she met someone else btw). She was actually very rude to me towards the end of our relationship. I was sick and had to stay in the hospital for a week and she didn't visit me during my hospital stay at all. It was the first year of covid and I could only get one visitor a day. Like and idiot, I told all of my friends and family not to come to the hospital to visit me because I was saving the visit for her and she never showed. She had gotten me a dog for my birthday but when we split she gave my dog away the following day, after I had told her repeatedly that I wanted my dog. She gave him away the day after I got out of the hospital. I distanced myself from her, even though she would still call me (she only called twice). I wanted to allow her peace and happiness in her new relationship so I left her alone. Also, I wanted to give myself the space to heal so I had to completely cut off communication with her. Anyway, I may still think about her a lot because I actually loved her. She was the first personal I had genuine love for in 5 years.
