My best friend is now dating this girl we both used to work with. Back when we worked together they had a brief fling. After I moved onto another job her and I would just chat to catch up and would joke around a bit. But we never did anything. But she did once say mention how I’m more social or talkative than him. Anyways fast forward five years later. My best friend and her are now actually dating and I’m so happy for them. But she’s now started messaging me quite often and she always tries to extend the conversation when I’m trying to end it. Cuz I feel kinda weird talking to her so much cuz she’s dating my best friend and I have a girlfriend. Am I wrong in thinking she might like me?
