I'm pretty new to this too, only about 3 months into a poly lifestyle. What I read in here is that it is tough at the beginning but it does get better. Poly is such a new idea when you have been immersed in mono ideals. It's scary, it sounds crazy, and you are always second-guessing (I know my husband is). The idea of compersion is the most beautiful thing I have found here.
When you love someone, it's always worth a try to explore new ways of loving.
Congratulations for your willingness to keep an open mind and heart.
Love is worth it!!!
