Why does my gf get mad when I like other girls facebook pics when they are my friends?

[Formative]

My girlfriend is the jealousy type and gets upset over every small lil thing for ex if I like more then one of my friend pics who are girls she gets upset r if I tell a friend who's a girl on Facebook who writes am ugly I tell her she pretty my gf gets upset it's not like am going around telling random ass girls your hot r pretty r likening rd girls pics. am not Type jealousy myself so don't get why she gets upset. If I was the jealousy type I'll make her remove the pics of her ex she has up there with them at prom but I don't becuase that was a big part of her life. I tell my gf all the time she pretty n when I close my eyes I see her kissing me. O just to let u guys know we were friends but now we are dating one another n she knows I don't date girls just to date them I only date girls I can see myself marrying later in life that being said she's my first gf. Sorry for the miss spelling n things it's been a while since I last had to write anything.

Tell her while holding her hand or hugging her from behind and say " you are the only girl I would do this with, I love you and not any other girl, I'm only trying to be friendly and not make girls feel bad for being different".

A lot of girls are like that it isn't she is jealous she is more territorial about fact you are hers and not the other girls she will simmer when she realizes its nothing you just need to show her all your love

Haha simple answer...she has trust issues and low self esteem. I was like this before but guys told me its a sign of weakness so I changed. She doesn't trust you obviously. She doest like her self enough either if she is jealous. A jealous person doesn't think high of themselves.
