So I was in a relationship with this guy for 6 months not knowing he had a girlfriend for 5 years. the girlfriend of 5 years lives in another part of town that's about 20 min away. When I found out that he had played the both of us so well I told her i was sorry and had no idea he was already in a relationship when she confronted him he lied and told her I was making it all up. I left him for good but the girlfriend took him back. It's been 2 months with no contact of him but yesterday he randomly messages me. I have no idea why he did!
