QUESTION: Did my ex ever loved me?

STORY: We were in a relationship for 6 years. It was all good for about 60% of the time and then she stopped caring about me. Wouldn't talk for weeks and if I would try to talk she would ignore. If I would complain she would say it's career related. And when we used to meet she was always in her phone talking to her friends, giggling and stuff. This got worse so I had to leave her. But these questions still haunt me.
