5 Ways to Deal with Your Boyfriend Flirting with Your Best Friend
4. Take help from your BFF
You might want to avoid getting her involved, but now it may be necessary. Talk politely and directly with your friend about the situation. Get a clarification from her end. See what she has to say. If you get the feeling that she too is attracted to your boyfriend, then it’s time to leave both of them. But if you feel she is on your side and has no such intention, it’s time to get the guy on track.
5. Make the decision
If you decide that you are done with the relationship and can’t handle this behavior of your boyfriend any longer, it would be wise and best to end it there. If you think you still want to work on getting things right, talk to him once again, this time more directly addressing your real concern. Or probably, you could use his trick, may be flirt with his friend and thus make him realize his mistake.
