> but I often wish for more connection with other people
The fact that that's not ok in your relationship sounds pretty bizarre to me. I am in a monogamous relationship, and I have both male and female friends. My gf also has both male and female friends. When she wants to go have some personal time with her friends, I'm supportive of that.
I'm likely reading too much into this, so I'll apologize in advance, but not being ok with your significant other spending quality time with people they care about seems jealous and insecure to me.
EDIT: My reading comprehension is apparently trash tier.
