Is OTHER wrong in the post ? POST : So some background on the situation

My fiancé’s (23M) father is emotionally abusive. Not better way of putting it. Things came to a breaking point a few months ago when he threw my fiancé out of the house with no warning and no care of what happened to him. Thankfully my mother stepped in and offered for him to stay in my room at our house while I am off at college.  We do have plans to move into an apartment together once I return in a few months.

After this incident, my fiancé cut all ties with his father, and we both decided that neither of us want him at the wedding.

HOWEVER, after mentioning this to several other family members and a few friends, I was told that we were being unreasonable and should forgive him and invite him to the wedding, as it would not seem right if he wasn’t there.

Are we in the wrong here, or should we stand by our decision?
