so i've been on and off with the same guy for about two years (its been tough because of the distance). although recently we've been talking again and he asked what i was doing on my bday and flipped out when he heard guys were going to a pool party with my friends and i. hes been pissed and hasnt txted so i tried talking to him two days later and he shrugged me off and said "he was busy" and couldn't talk....
i just need to know am i at fault? and what should i do next? i dont want to come off as desperate because im not but it bothers me that hes still angry with me..
