Dream about getting back with an ex-boyfriend? Please?

I had a dream about getting back with my ex boyfriend last night. We were sitting outside in the gr on a hill. He kissed me really hard, but I pulled away. He didnt seem to notice or care. It felt so real. He put his arm around me all smug, and I put my arms around his waist like I used to. We sat in silence, but it wasn't an awkward silence. I felt happy, but sad at the same time, because I knew he wasn't right for me, and yet it felt so right. My emotions were really conflicting. What does this mean for my subconscious? Thank you.
