SUBREDDIT: r/relationships
TITLE: Me [23 F] with my boyfriend [21 M] of 1 year, do I have the right to be annoyed at him for staying out late with his/our friends?
POST: My live-in boyfriend and I used to have the same friend circles that were largely co-ed... a healthy number of girls and boys. This friend group has since drifted apart and I am now one out of two girls in the friend group, the rest are eight boys that my boyfriend and I get along very well with.

The other girl in my group is in a relationship with someone that occasionally but very rarely hangs out with us, so now most times she is off hanging out with his friends, leaving me to be the only girl in the group. I generally get along with boys more than I do with girls, due to growing up a little bit of a tomboy until the age of fourteen (I climbed trees, ripped dresses, dressed in baggy boys clothes, had short hair etc etc). 

That being said, my boyfriend and I had a talk about me finding more girl friends and maybe hanging out with the boys less for it to be healthier as the boys sometimes could not have 'man' talks with a girl around. I completely understand, even though I do not mind, and am used to these chats (that revolve around cars technology and women).

So sometimes I go off and have alone time or hang out with some of my other friends from the gym that I do not see very often.

I have no qualms with him going out with these boys for dinner/drinks, but this past week it has been 3 nights in a row. The rest of these boys are single, and my BF is the only one in a relationship. I want to tell him that staying out until 2am and coming home only when I text him is not ok, as it is making me feel as if i'm his mom. I do go out for drinks as well, but I come home at a reasonable time. Needless to say, I am annoyed. How do I approach this? Am I being unreasonable?
TL;DR: 
BF stays out late with friends til 2am for 3 nights in a row. Am annoyed. Am I being unreasonable?
