I have so much heartache

[Its alittle long but please help, thank you] Ok so it started out I get a message from my girlfriend (she lives in a different state) and she asked me if I was hiding something from her. I don't hide anything from her, I love to tell her everything...

thats going on with me so I asked what she meant and she started accusing me of cheating on her. I found out later she looked through my pics and found a tagged pic of me and my friend Jennifer. So my girlfriend automatically assumed I was cheating on her??? She said because we were sitting on a bed and that Jennifer had shorts on and it looked like we just got done having sex???! I don't know why she would even think something like that, my girlfriend means everything to me and she always has and without her I would be absolutely nothing. She's not just my girlfriend but she's my best friend and we both gave each other our virginity. I love her with all of my heart and it hurt so terribly for her to accuse me of cheating without any evidence of anything at all and not believing me when I said nothing was going on. And then I found out that on her assumption that I was cheating (before she even talked to me about it) she had been crying and she had told my best friends that I was cheating on her thus turning everyone I know against me, so now everyone hates me and wont talk to me so I can tell them whats really going on. I have so much heartache and its making me sick over it =( . Please help me, what am I supposed to do?

tell her that it was just a friend and shorts do not resemble having sex on a bed!!!

I told her that but she dident believe me

just try to talk to her and explain that you did not cheat on her

if she truly loves you she will listen

other than that you cant really speak to someone who doesnt want to listen

well you mite be betta off...I know you love hur but you mite wanna question da mental state of someone drawing a silly conclusion based off of of a pic of you and a friend...that just doesnt sound rite...usually those that accuse are da ones that are doin it but dis mite not be da case...people that really know you wouldnt believe sumthin like that without speakin to you about it first so you mite wanna question that too...I just got out a relationship wit a girl that accused me of cheating all da time it wasnt bc she was da one cheating but bc of hur past...she was used to getting cheated on and thought I'd be like all da others...well it didnt work out but I'm glad it didnt bc she turned out to be a psycho...
