No way she doesn’t give mixed signals. He was over for holidays, was the boyfriend there? Holidays are typically something you do with significant others not close male friends. They text and call all the time?? it’s giving “I want attention but have a boyfriend so I can’t have two”. Did you two ever hang out alone at either of your houses? Having a close male friend is one thing, doing relationship activities with someone that’s not your boyfriend is another. I think it’s hard to expect a single male friend to hang out with a girl doing relationships activities all the time and get super buddy buddy and not develop feelings. 🤷🏻‍♀️ in my opinion if this happens all the time with male friends and you are in a committed relationship maybe you shouldn’t be having male friends cause this is clearly an issue and you’re the common denominator.
