Is my mood unfounded or would you feel the same?

I do feel the same. My boyfriend was supposed to come to my new years eve party, well he ended up going to his best mates one. I did feel reli upset at first, i mean all girls must, and you and him have been going out for a long time, if your really close and you must see eachother quite alot (i know i do with my bf), then its better if youd let him go to his mates party, yes he is being selfish but in the end he will be even more happy to see you, give him a little bit of space, he will thank you for that. my boyfriend missed me last night anyway. It will all get better in the end :) i hope that helped :) xx
