My boyfriend txted me to tell me he was online so could play a game with me at 10pm. He's had a really hard day today with his friend being seriously ill, I've been texting throughout the day about it. I said sorry but I was at the river with some friends and asked how long he'd been up. to which he replied 'wtf'. then asked who with and i told him and he replied 'right'. i said i was going back now anyway. no reply. asked what's up, if he wanted me to call him. no reply. said i wasn't drinking, if that's what he thought. no reply. now i'm freaking out because I know i've done something wrong and i think it's either because I was hanging out with someone he doesn't like (but he knows we're friends) or that I should have been at home waiting for him to call because of his day. but he won't tell me, so there's nothign i can do but worry. what can i do??
