am I a whore ?

Brittany
Okay so by boyfriend is in the marines and let this be said I never cheated on him. he graduated already and this is my senior year I had friends but they all graduated this last year I tried making new friends but they were always starting drama or had drama going on so I keep my distance and I sat alone for the longest my guy friend started hanging out with me and on wed I go to church with him and we went to Disneyland as friends well we hang out often now still as friends but those girls called me a whore and said my boyfriend deserves better. Is it bad I hang out with a guy ? Like i consider this guy as my best friend because he's been so nice to me. Like I can't let this go it hurt me. I told my boyfriend to that we hang out he's kinda jealous but said it's fine that he trust me. But is it bad should I just stop being friends with this guy? Here's a pic of both of them
