Do I actually cheat on my boyfriend?

I have a 2 years relationship with my boyfriend we had a good relationship sometimes ? But we argue all the time because he always choose his friends over me . I was in a mall that night doing our thesis . On my friends laptop. Then suddenly someone just called me on my phone asking where am i and he said he's also there . So he came to me he invited me to eat dinner so i said okay . We eat in a fast food chain and talk about my boyfriend and his behavior he is my boyfriends Friend . And then suddenly he ask me to come with him because he is going to meet a friend in a bar and he doesn't know where it is . And i said i will just call him but my phone is already dead and also his phone . So for me maybe its okay . So we go to a bar and listening to acoustic band out there . Then suddenly While waiting i just had a 1 glass of ladies drink and then i get dizzy i cant see a thing and the last thing i know is that we are entering in a room so i get in to my senses and i slap him ! I slap him and curse him he cried and says sorry . because of crying and my loud voice i got difficulty breathing he rush me to the near hospital then he continuously saying sorry to me. And the next day i tell it to my boyfriend and he is not convince that nothings happen to me and his fucking friend. I dont know what to do now that everyone knows it especially his parents.

What do you suspect? That this guy slipped something into your drink? Do you think that? What did the Drs say? Look - all these guys are not good for you. Your boyfriend does not sound suppportive of you. The fact that you argue all the time says a lot about him and your relationship. Why are his parents involved in all this? You seem to be blamed for something. What is it?
