<human>: My boyfriend and I have a group of mutual friends. However, when he hangs out with them, he doesn't invite me and it genuinely hurts my feelings. It doesn't hurt my feelings when he doesn't invite me to hang out with *his* friends because I know that he needs time alone with them, but I feel really left out when he and our mutual friends are out having fun and no one invited me. 

I've told him once before (a few months ago) that it hurts my feelings when he doesn't invite me to hang out with our friends, but he said sorry and not much else. Now, he and one of our friends just publicly made plans for the weekend (as in, I saw a post on Facebook) and I'm fairly certain that I'm not going to get an invite. To specify, it's not going to be a boy's night out or something like that, the friends in question are females. I'm sad because I feel like neither my boyfriend nor my friends want to hang out with me.

I don't know if I will say anything to him about it if he doesn't invite me. Is it unreasonable to be upset and feel left out? Should I just let him have his fun without complaining?

Can you condense the text into a few key points?
<bot>: My boyfriend doesn't invite me to hang out with our mutual (female) friends and I don't know if I am being silly for feeling left out.
