<human>: So I've been dating my 17 years old girlfriend for about 2 weeks now, its just the begining of it but we really like each other and we have been spending a lot of time together when not at school.

So me and my class, 11th grade studying art, planned to go to the city(porto) for a afternoon to go shop together and hang out as we are from a small town. 

So this is were it comes the mess in my head, I really like her, but I really like my friends and I just wanna hang out with them at that day and have some fun with them, but the problem is that the people that are dating in my class are taking their boy(girl)friend with them, and I dont mind at all, I just would rather go alone, but I have a friend in my class that is a close friend with my girlfriend and she invited her to come along with us without asking me first, assuming i wanted to take my partner as the others are taking theirs.

So she comes talking to me and tells me that she is invited and wants to go with me, I just dont know what to do please help

Provide a brief overview of the text.
