<human>: A bit of backstory: Me and my bf have been together for 11 months. A couple ago I found very flirty texts between my bf & another girl (I'd been suspicious for a while since there were certain times he would angle his phone away from me, or would only answer it after I'd left the room). He always initiated the flirting with her. I confronted him and he promised it wouldn't happen again and let me look at his phone any time I wanted after that. I only took advantage of that twice because I want to learn to trust him.

There was also another girl who was obviously trying to get with him but he wasn't very responsive at all. He brushed her off. It seemed like he was totally uninterested. But whenever he likes her new profile pic it shows up on my feed so maybe I was wrong. She's also invited.

I woke up this morning and he sent out invites on facebook. My heart dropped because he invited both of these girls and I don't know how to feel. I feel dumb for being hurt - it is his birthday, after all, and  they've all been friends longer than I've known him. But it's compounded by the fact that we haven't had sex in 2 months. He's very stressed (debt, bills) and is worried that I'm going to have a panic attack during sex (because of my PTSD) so part of it is my fault. But I'm scared theres something more to it.

And I don't know how to talk to these girls. I'm not going to be a jerk to them, I'm a very nice person. But it hurts a lot still no matter how stupid it may seem. I want to talk to him about it but its not that I don't want them there, its that I want him to be honest with me in whether he's still flirting with them or not. I don't feel like his girlfriend. I feel like his snuggle buddy who lives with him. He's already stressed enough I don't need to add to it. I'm very confused.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My bf is inviting a girl he's flirted with and a girl who obviously wants to get with him to his b-day party. Do I have any right to feel upset? Should I keep this to myself?
