First timer here, I don't want to write a novel so I'll try to keep this brief.

NP and I met a new person who has slowly formed a connection with us and it's been great, but when trying to set boundaries there seem to be some issues coming up and it's causing me both a bit of frustration and anxiety.

The thing I was requesting is for my partner to allow me and the new person to connect and do things on 1on1 sometimes, NP claims it's fine but makes him feel left out, despite me also giving NP this allowance, and despite agreeing during our therapy session to start doing things away from each other since we've been a bit cooped up due to nasty weather and work.

NP prefers our interactions to always be as a throuple, which I find very unrealistic and is going to wear us thin. Before even seeking new partners we both agreed that while we wanted to do lewd things all together with whatever arrangement we would form, it was also fine to seek new people out separately. We talked so much and so deeply about our boundaries almost every day, and now that there's a potential to come to fruition it's different.

New Person and I formed a bit of a stronger bond compared to the bond that New Person NP has formed. NP has someone else that he connected to better than I did and was quite attracted to. I've encouraged him to reach out to this person but he seems to only hyperfocus on the one who I am connecting. It makes me feel a bit of discomfort, maybe a little bit like he HAS to also have what I'm having, or else I'm not allowed to have it at all. New Person likes spending time with both of us though whether it's just hanging out or in bed, so it's not like it's forced or pressured.

Maybe I'm just seeing this all wrong, any insight or advice on how to talk about it further with my partner would be nice
