Newbie here, me and my GF have started or journey into polyamory recently and when she goes on a date I feel really weird. In my head I'm happy and I want her to have fun and enjoy herself and I make sure I do everything I can so she knows and is sure I'm totally ok with it because this is the kind of relationship that we both wanted.

However, sometimes I feel this weird feeling as if I was being cheated on. My only past relationship was monogamous and lasted 7 years so I assume it has to do with somewhat of a learned reaction to the events that are going on.

Is is normal to feel this way even thought I know in my head what I really want? We communicate a lot and I've told her about my feelings so she can be more reassuring of our relationship which really does help a lot but I'd like to hear if other people experienced things like this when going from a mono life into a polyamorous relationship (at the beginning at least if not later).
