Ah yes, you start seeing this guy and he's super incredible. He's everything you could've ever hoped for and more. He's sweet to you and your family, he's loving (bonus, he's also super cute). Nothing could take away this incredible feeling.
Then he tells you his best friend is a girl.
I can't lie, it always rubs me the wrong way too, at first. I've been in a relationship where I was seeing a guy who had a girl best friend. And despite better judgement, I let it slide. Only for him and I to stop dating and he start dating her a month later.
But I can promise you, it isn't always like that. Is it scary to think about? Of course. When my current boyfriend had told me I was going to meet his girl best friend, I wasn't thrilled about it. As sweet and nice as she was when I met her, I still wasn't thrilled about it. We had just started dating, so I hadn't yet gotten over those insecurities yet.
Questions ran threw my head. Had they ever had feelings for each other? Do they have feelings for each other and just won't act on them for the sake of their friendship? I couldn't seem to get my head to stop.
Until I started to talk to her more.
When I tell you, the best thing you can do in ANY relationship, is become friends with their best friend. They know everything about your significant other. The good, the bad and everything in between. You'll learn more about your boyfriend/girlfriend from their family and best friend than you will from them. You see a different side of them when they're with them.
To say I was apprehensive at first is probably an understatement. It didn't help that I had this awful gut feeling that she hated me. (BTDubstep, her and I are best friends now). But, after letting go of those insecurities and getting to know her, I realized that there was no form of intimacy or flirtatiousness between them at all. I had no worries because I trusted both of them.
She actually lives with him and his other brother. People always laugh at me when I tell them that because they think the stereotype and assume they have a thing. I love my boyfriend, I trust my boyfriend. I love his(and now mine) best friend, I trust her. There's nothing we don't share with one another because all 3 of us are very open with communication.
Just because your significant other is best friends with someone of the opposite sex, doesn't mean they're in love with them, or that they are trying to sleep with them.
Take the shot, the worst that happens is they do have a thing and you break up. If that's the case, they aren't right for you anyway. But take the shot, you might even gain yourself another best friend.
I know I did.
