I’m not sure where to begin really. I’m fairly new to poly. My husband and I have been married for 13yrs and we’ve been mono for those yrs we have two kids. My husband has this friend that we’ve both know since before we were married. There has always been an attraction between us to the point where we all nearly had a threesome, before we were married. The friendship has been close but sometimes on and off over the years. Just recently it has started back up again and we’ve become closer. My husband and I discussed if he was ok with it progressing more. So currently I go over to his once a week or twice a week in the evening. It has become sexual. I don’t know where to go from here. How long I want to be in a secondary relationship for. My husband and family life are completely different to that of my bf. I connect with my bf in a very different way to my husband. Me and my bf have discussed this being long term. My husband has had some insecurities. He has said our relationship hasn’t changed in fact we’ve become closer. Just need a little advice and insight of how to move forward. Should I just let it ride and see where this all leads?
