<human>: Can you condense the text into a few key points?

So I recently came back for a family vacation to see my girlfriend for New Years. She had a friend come to the same party as us who was visiting for 10 days from another country. We both confessed our love to one another at midnight (NAWW) and hungout in a room upstairs the rest of the night. I can imagine her friend would be really upset as she hooked up with a guy she didn't want to... and was really awkward throughout the party causing her to get to a drunkness that she didn't want to reach. My girlfriend told me when I arrived home after the party that her friend dind't like me very much... I expected it just to be because I was with her the entire night. 

However, when I tried to hangout with them on a "hangover walk" it was extremely awkward... I'm a guy who gets along with literally anyone and everyone, except for this girl. I just could not click with her at all.

Since the walk my girlfriend has been acting really weird, talking to me a lot less than when i was on vacation. Her friend has been here for a almost a week so it definitely has nothign to do with her being her. I have a feeling her friend is trying to convince her not to talk to me? because when I asked her to hangout the other day she said we would everyday when her friend was here, and now she doesn't want to hang at all.

So Reddit, should I let them be enjoy their company for the next 3 days even though I haven't had the chance to soberly hangout with my girlfriend in 3 weeks? Or do I try to come to terms with her friend who really dislikes me?
