so ive been in a relationship with my girl for 2 1/2 years now. its a great one to boot and it was my first on. throughout the time weve been together i couldn't help but thank her and whatever it was that made me so lucky. but recently im not sure if im being paranoid or not but, the thing is she is bisexual and well it hasn't really come up a whole lot but nowadays we hung around with a couple of our friends and they decided to introduce us to another friend of theirs. my girlfriend and this new friend relly hit it off well. as if they just clicked. saying things like "how come we didn't meet sooner or i like her." at one point when we were going out she pulled up her phone and talked about how the girls dress for her friends wedding is so pretty and how great she looks in it. furthermore shes told me that" no offense honey but if we weren't dating i would date her." granted this was said in a more playful manner. but i cant help but think is my girlfriend growing feelings for thjs girl weve met about 4 times? please i need advice on this.
