I (31 M) and my girlfriend (30 F) have been together for 10 years. We decided to do polyamory a couple years ago. She had a relationship which ended. I recently started a FWB relationship with a girl. Me and my gf agreed it wouldn't be romantic, but we both (FWB and me) ended up catching feelings for each other, as we found out we're very compatible. We deescalated our relationship and only talk in person like 2 days every 2 weeks. The problem is this made me think I may no longer be so compatible with my gf and I don't know what to do. I don't want to break up with her, I really like how compatible me and FWB are. I've talked to my gf about this and how I'm feeling and that I don't want to make any decisions. We're working on our relationship, but I'm really scared of not being compatible
