Would you have a small break from your fiancé if you are struggling to forget the times he’s disrespected your boundaries and also

lied about disrespecting the boundaries you set?

I’m thinking of just staying at my mums for the rest of the week to get my mind set on what to do because i have really bad trust issues and this has made it and me so weak and sad i’m struggling to overcome and forgive it. Just need some alone time to think.

Is this a bad idea?
