My engagement ended

I was introduced to my neighbor's son and we got along I wasn't a practicing catholic but after meeting him I found more faith in god, I didn't share everything about my past with him just a portion and he used to torture me with it, so I didn't share everything thinking I could just get married and put everything behind this torture continued for a year but I wanted to believe it will change it didn't we went for our marriage prep and we fought there as well. And finally it went to heads yesterday, We broke up because when we were out, I went to say hi to this girl i knew and I knew a guy from there and he came and inappropriately touched me and my fiance blamed me for not reacting and accused me for being shameless.

So this is the end 1 year I tried everything kept lent, did the rosary, attended retreats just so my marriage could work. I feel so low and broken.
