<human>: Okay, so this is a bit trivial but I'm feeling unsure about what to do or how to feel about this situation... My boyfriend's friend (let's call him B) invited him and I to his birthday party sometime in February. B also invited two other mutual friends of ours, we'll call them D and C. D is dating C and C is best friends with my boyfriend's ex. D, C and The Ex all live together and so C invited The Ex to B's party. 

I'm sort of uncomfortable with The Ex being there because she still has feelings for my boyfriend and has tried talking to him and seeing him since he and I started dating almost 8 months ago. I told my boyfriend all my thoughts and he also thought it might be a bit weird/awkward but still feels that we should go, which I understand because he hasn't seen B in a long time. He then suggested I stay at home but I'm also sort of uncomfortable with that seeing as they'll all be drinking and then staying over at the same place. I trust my boyfriend, I just don't trust her; so I have no idea what to do or what to say to my boyfriend. 

I know I should probably just suck it up and go, I'm just scared that she might try to confront me or say something to me and I happen to be a really socially anxious person, so even going to a party would be hard enough for me, let alone having to worry about her and the rest of the people around me. 

Sorry if this is a bit confusing or if there's spelling or grammar errors, I wrote this all on my phone!

Can you give me a shortened version of the text?
<bot>: Pretty much what the title says. Boyfriend wants to go to an old friend's birthday party but his ex girlfriend will be there.
