I started dateing this guy in August and things were going great for us. No fighting or anything. We had talked and planned on moving in together after the holidays and he even went out and bought an entire set of bedroom furniture for our place. He went through a lot of trouble making me feel special. He bought me a beautiful ring we met each others families. He got sick and felt bad we missed 3 days together so he brought me flowers. One day he took me for a drive showed me where he grew up and took me to his grandparents ranch out of town and told me they weren't home but he wanted me to meet them. On the way home he started talking about when we move in together, when we get married, when we have kids. All brought up by him. 2 days later when i talked to him he ended it with no explinations as to why. He quit talking to me all together. It took me a while, but I finally moved on. Now after 4 months hes decided to start texting me again like nothing at all happened. What should I do
