My BF wants me to move in but still co-sleeps with his 2 children, son age 6 and daughter age 8 and expects me to sleep in one of their beds on the nights he has them so he can continue his co-sleeping. I don’t want to move in on the basis that I won’t even have my own bed or bedroom and have to move out of his/my bed to accommodate it, am I being unreasonable? Should I just be accepting of this situation?
