Dingedhearts questions are really good ones.
Try not to panic.
Early poly is often fraught with mistakes and learning experiences. Often, people get carried away with NRE (New Relationship Energy) and can start acting like kids in sweet shops. However, it doesn't have to stay that way.
If it helps, I'm only 16 months into my poly relationship and the first 6 months in particular were quite messy. We both got carried away with the wrong people and acted almost like single people. It took a massive amount of communication and even now, we still make errors sometimes, but poly is something we genuinely love and appreciate.
I'd love it if you could tell us a bit more, some of the background, some of the issues in more detail.
