What's your opinion?

i've been dating for the last two months and even though i havn't been very serious with them, i've had them meet my dad who lives with me. i think that anyone that can't except my dad can't except me. well, it's been like a revolving door with guys going in and out. i didn't like anyone enough to become committed to so i just moved on to the next. this girl (that i truely detest) basically called me a slut because i have all these guys coming to my house. i haven't slept with them because i was just trying them out so i couldn't be a slut. there are other reasons much worse than this that makes me detest her, but is she right? am i a slut?
