My gf(bi female) and I (straight male) have been together and mono for about 9 years. We have losely talked about going poly, and earlier this year she made the decision to go poly, as she wanted to Date other women. Over the course of a few months, she has had great luck with matches and dates. I on the other hand, have not. I recently started talking to a girl who was ok with the fact of me being in a enm relationship. We have worked up to trying to meet for a first date, but my girlfriend admits she is uneasy about it. She tells me she understands she can't hold me back, and it would make her hypocritical, but she is struggling with insecurities and jealousy over it. I obviously don't want her to feel like that, so I myself have been putting off progression with the other girl I am talking too.

We are both very new to this being about half a year since we opened up to trying. What can I do to help her with these issues? I don't have any issues with some of the girls she is seeing. So I want her to be secure with me with the people I am talking to as well.
