My partner and I have been together for 8 months, and we just moved in together.

When we first got together she already had a girlfriend, and I was polycurious. We got close very fast and I dated a bit during the beginning of our relationship but quickly realized I didn't have much of an interest in seeking other sexual or romantic connections. My partner and her girlfriend broke up and there were dates here and there but over the last two months or so we haven't been seeing other people.

This week my girlfriend informed me she had a few dates set up. I started feeling really negative emotions towards that and so we started talking about it. She's newer to ENM as well and we realized we hadn't really discussed feelings and boundaries regarding that.

So now we're trying to figure out a solution that let's us both be comfortable. But I don't know where to start. The while concept of ENM actually makes me quite uncomfortable and I don't have enough experience to know what kind of boundaries would feel right.

I don't want to make rules regarding her life, and her bliss. But I can't make the bad feeling stop. But I also want to at least give it a chance before I throw the towel in.

Where do I start??
