Let's say your boyfriend has female friends... can be anywhere from a single female friend to lots of them.
How do you know if your boyfriend is interested in his female friends, or conversely that his female friends are interested in him? Where do you draw the line between "hey this is threatening behavior" and "I am being paranoid?"
In a past relationship, my boyfriend was very, very good friends with several girls. At first I didn't have any issue with it. But as the relationship continued, I became more uncomfortable with some of these close friendships. One in particular felt very threatening... She would call and text all the time, if she was in town and staying at his house I wasn't allowed to visit (I lived about an hour away and he said he couldn't handle "two guests"), he talked constantly about how smart she was and what a MASSIVE crush he had on her in high school; friends of hers even assumed they were dating.
Now as I'm getting back into the dating world, I feel as if I'm prone to oversensitivity about what is platonic friend behavior and what is romantic friend behavior. I know I should be trusting, but I also don't want to be naive.
