We've been talking about this a lot, but neither of us have any experience first hand. Background: She has been dating Kevin (not his real name) for over a year and it is getting serious. She has two girls in college and one son, who adores his own father, who is fourteen. Kevin has a daughter who is in eighth grade (seems like a nice kid) and a son who is elevin. Both children are VERY attached to him as he has been the primary parent, although they allegedly live with Mom (she is not with them half as much). Before Kevin met Sis, his life was his kids and it still sort of is. Sis and Kevin have decided that it is time for them all to meet. Sis is going to meet his two kids first. She is wondering how this changes a relationship. What is a likely reaction to her from these kids? How does it change the relationship's dynamics? Since I couldn't help her I thought I'd ask you. I know there is a lot of experience here.
