After a falling out, can there be forgiveness & mending of a relationship?

This was a relationship involving 2 people in 30's. Everything was going as good as it could. Both of us were happy, enjoyed much spending time together, sex was great & often, planning to live together(she asked about kids in the future). But we had a falling out (i used bad judgment, made a mistake, not cheating,she felt i crossed the line w/ her body, i felt she over reacted & we should have talked it out)a couple of weeks ago. She got extremely upset & stated that incident remind her of something from her past. i knew nothing of this. obviously i never would have intentionally hurt or upset. she went on a weekend trip w/ some friends. when she came back she ended relationship. we never talked. i felt horrible, guilty, & eventually angry at her. I miss her very much & am wondering if one feels so upset can their views change considering that we had such a strong bond & were making plans for the future. We were nearing the point of using the "L" word. I have given her space as i know it is best. Can we get past this & move on?
