were dating for 2 years now, my boyfriend and i and on sunday we were invited to my best friends b'day party that all my friends attended. ae arrived at 3.30 pm and at 4 o' clock he got an sms from a close friend of his, whom he shaw the previous day at a friend's house. he asked how long did i think were staying so he can go home and join his buddy who wanted to come over and play video games. hes 33 yo. its been 4 months since i shaw my friends and it was a special occasion. dont you think he should've rejected his friends' proposal without even asking me about it? it became nervous instantly for putting in such a position and i said pls leave it open or at least make it around 8. and so he immediately fixed his date. so now i hat two choices to go with him or to stay with my friends and no ride home. whos the selfish person here? am i exagerating or my boyfriends is too self absorbed and immature? thanks for your help anyway...
