Am I right to be slightly angry at this? Long question?

Sorry but this girl sounds pathetic of course you have to plan things can't just drop things just like that, I think its good that you want to spend time with your family and if things are difficult its good that your sticking by them, Just shows this other girl doesn't understand and mustn't get on with her family very well then, my mates still ask me out but I have to say no most of the time because of money, If this girl stops asking you to go out then just got to think so what she can't be that understanding then, Your right you have to plan things ahead sometimes,You know who your true friends are because they wouldn't stop asking you out and would understand, I wouldn't even bother with this girl just doesn't sound worth it and its like she is only thinking of herself! Sometimes spare of the minute nights do work out ok, but not all the time that's why you have to organise some! I think if you went of with that girl and not with your family then you family would have been peed of you did the right thing.
