My BF and I are also new to the poly lifestyle, though we're a little different in that we came to being poly together. We did, however have a few snags here and there due to jealousy on his part and communication issues at the beginning on both our parts.
you're in a learning process here, and it's not always going to be perfect. We had our screwups, and we got through it together and our relationship is now much deeper and more passionate that it ever was when we were mono.
good to hear you guys are moving together in your relationship.
Stick with it!
