Do you think it's good I broke up with my girlfriend?

She was not too enthusiastic when we were hanging out, she didn't text back quickly, she was always too tired for me, she texted with a guy although he had a girlfriend and she was still with me (saying it was friendly and that she would break up with me if she were attracted to another guy), she told me she was not as attracted to me anymore.
