Did I make the right choice?

hey guys. I broke up with my ex gf who I was with for 1.5 years a couple months ago. I think it was the right choice because my issue was that I felt so uncertain. She is an amazing girl and I care for her so much. I really thought I would marry her. Our first year together was great and we were so in love. At the beginning of this year though I started having doubts. I didn’t really wanna text her every day and when we hung out I just wanted to be alone. I also didn’t know if I loved her truly or just had love for her as a companion and friend. I broke up with her a couple times bc of that but I would come back within a few days begging for her forgiveness because the days without her felt like hell. When we’d get back tg I would feel those butterflies again and it would be amazing for a few weeks until it didn’t. She asked me if I still felt that way and I told her I was still uncertain so we took some time apart to not talk so I could sort my feelings out. Truth is I didn’t want to leave her and it hurt me so much. But I wasn’t feeling super excited in the relationship either. I just wanted to be alone. Ppl also told me that you should feel 100% into your relationship if you really love them. After a break I officially broke up with her and she was a mess crying and begging me to stay. It hurt me so much and we cried together but I still left. It’s been a couple months now and we are strangers we don’t talk at all. I miss talking to her and hanging out with her. I still am attracted to her and don’t want to be with anyone else. I just feel like I’d be doing both of us a disservice if I went back because I feel unsure. I know she’s still waiting for me and if I wasn’t unsure I’d go back immediately and commit for life. I just don’t know.
