NMom ruined my engagement

My narcissistic mother ruined my engagement. She planted seeds of doubt in my mind about marriage, my career, religion, and generally made the planning process horrendous (all under the guise of “caring about me”) and I stupidly had no boundaries and gave her free reign to my emotions and anxieties about the future.

I am trying to give my fiance time and space away after recognizing and explaining the situation to him, but he completely freaked out and shut me out, at least for now. He was the love of my life and was perfect for me in so many ways. I am absolutely crushed, and my mother in some part of her sickeningly likes that I am unhappy.

Is there any hope for me/us?

I’ve decided to go NC with my both my parents for awhile as they are both toxic for my love life and self esteem. They would have issues with anyone I date and really think either of them don’t really want to see me get married (they are both divorced, never remarried and are miserable).
