Is it normal to have a "semi-closed" open relationship?
I'm an 18 year old girl, almost 19.
I've been with my boyfriend for years, and we both love each other very much. We definitely will get married in the near future.
However, before I met him, I had a very close relationship with my best friend (also a girl) and we recognized that we might have feelings for each other beyond friendship. Years later, even with my boyfriend I have felt these same feelings for her, while not feeling anything less for him. And recent contact with her confirms her feelings for me as well.
Talking it over with my boyfriend, he is perfectly fine with her entering our relationship. And by "our", I mean mine. What I mean is: He will be with me, and she will also be with me, but they will not have any sort of relationship with each other. They don't like each other in any way past "acquaintances"- and to be honest, I wouldn't want him touching her nor her touching him- I'd get jealous. But it seems like both of them won't get jealous that I'll have another...? I'll be the only one with two relationships, whereas they will each have only one... I just don't know what to think.
Is it normal?
