why do i feel like this

Hi Laura,

I was in a relationship about 4 years ago, but as i was in the relationship i started realizing that something was missing and did not really want to be in that relationship. Once I just called the relationship off but I felt bad because i hurt him so we got back together... I guess i was rather confused, but i always had those feelings in the back of my mind. Once my mother found out and I called the relationship off for good. I felt miserable, he did not want to break up but i did not see any other choice. I did not feel as if i was really willing to be in that relationship but at the same time i was confused, but after that i got over it and started dating someone else and we have been in a relationship for 3 years now and i really love him. but sometimes i wonder if what i did was right or not, when i look back and think i know that i would not want to be with that guy... what is your insight on this situation? and how should i avoid thinking about my past?
