The fact that your husband slept at his ex’s place, without you knowing, whether something happened between them or not is a serious mistake. Of course, it’s not something you can just easily forget. It will naturally make you wonder if something did happen, and question whether he still has feelings for his ex. It brings up a lot of doubts and unanswered questions.
Maybe the best thing you can do right now is to take a step back and stay low-key for a while, and wait to see what happens next. Try to observe your fiancé and the actions he takes moving forward. After that, you can decide more clearly what you want to do.
In the end, it’s still your choice what you want for your life and relationship.
