man somtimes i think i get the short end of the straw all the time....yesterday i was chilling with my gf.....right......now she is very protective....about other girls being around me....yeah.....so today i see her hugging another guy..who happens to be one of her best friend's who i have no problem with..i mean i really don't care. i trust my girl friend. sure it makes me a little jealous but nothing to flip out over..(yes im a guy who actually admits i get jealous)..well yeah later that day i run into an old friend of mine back from middleschool....she runs up and hugs me... my gf walks out of her work and see's the hug..(i was at her work waiting to pick her up).. after putting on a false impression to my old friend that "we" needed to get going...that she had to get home and we had to go..once in the car....she chews me out...for letting her hug me.....i mean i like my gf ALOT........but somtimes i just feel like.... im not being treated fairly.. and i don't get the same amount of trust that i give her... . i mean in her past relationships she has been cheated on...but then again so have i....why should i have to get the bad end of that trust bracket. why should i be judged by what others have done to her before me. im not them.... i think this relationship is taking a turn for the worst.....cause im starting to get annoyed by it. Alot of my ex's are still good friends of mine....and this "gf" of mine is really starting to interfere with my relationships with my friends....please tell me what you think of this
