It sounds like you are passively accepting all these major life changing decisions that your fiance is making. Did you and he sit down and discuss each and every part of this and come to these solutions together? Or did you just allow him to arrange his family to flank about your cozy cottage? I might have said No to all or some of these decisions. I think you are going to need to set some boundaries with this man. What and how much family time are you going to be comfortable with? And what about him? I think you two need a marriage councellor or couples therapist. I see a lot of red flags that need to be addressed before going further. Just my 2 cents.
