I'm I wrong for not letting my sister come to my wedding this is the reason why she having slept with both of my kids father and tried my soon to be husband he told me that she tried him I don't know what to think or do
Do you have a relationship with her? Did she sleep with them while you were in relationships with them? If you do have a relationship with her, do you care if it's affected? Does FH feel comfortable with her being invited?
It sounds like you're second guessing your current relationship, and if that's the case, are you sure you want to get married to someone you don't completely trust? It seems to me that if your fiance knows the toxic history between you and your sister that he would want to stay completely away from her to not even give you a reason to suspect anything.
I highly recommend you seek couples therapy before proceeding with wedding planning!

This exactly hon. Way too much going on here to even think about a wedding.
Don't invite her. Don't plan a wedding yet. Figure out if he's faithful and work on building your trust if he is. She sounds horrible. I would never talk to her again after the first time. I'm so sorry!
