When I (22f) met my partner (23nb) they quickly came out as asexual. I am very much not asexual so we talked things out and eventually opened our relationship. We're long distance and I always made sure to keep them informed and ask about how they feel about some of my partners. We've been together since 2018 and they never were actually interested in anyone that wasn't me.

But about a week ago they told me that they had met someone and they think they'd like to pursue them. And I am terrified. Because not only this new person suddenly exists. Which hasn't happened in 3,5 years but they're also in the same city as my partner. I think their lack of distance is the part that scared me the most.

Like, I know my partner loves me and I love them back dearly. I do not wish to restrict them because, again, in 3,5 years of our relationship they haven't mention a single person they enjoyed so clearly this new human must be cool. But I feel super anxious and threathened and no matter how much my partner reassures me I just can't shake the feeling.

How do I even deal with that?
