Is this considered cheating?

My girlfriend has a friend who she gets very physical with. I know they used to cuddle and sleep in the same bed at sleepovers, they play fight and sometimes even hold hands, sit on each other's laps. My gf also used to invite her over late at night to stay with her until sunrise, but refuse to sneak out and see me when I wanted to. I was suspicious and went through her phone today to see their chat. The girl had travelled for a vacation and has been gone for a week.My gf said she misses her and everything, her hugs and cuddles that made her feel safe,comfortable,warm. She says "Oh baby your VN's are everything. You make my day." In 1 VN she said "im sorry I didn't call you back again, my boyfriend called but I'll call you tonight. I really love you, you're everything to me." She sends her photos of her cleavage and a VN of "You wanna see a video of me stripping? Bet you'll love it". They video called the other day and my gf was showing her, her bra. In one VN she also told her "my boyfriend is cheating on me and I want to break up with him, I don't feel the love I used to. Things are changing. And you- you're always here for me,whenever I need you, but he's not. you're the first person I think of ." The other girl told her "I love you so much and I'd to anything to make you happy but don't do crazy decisions right now." Then she told my gf that she's thinking of staying abroad to find a job. My gf teared up and begged her to come back. "If you leave my life will be f*ckd up and screwed up, you can't leave me alone.Youre like a parent in my life. I miss you and I love you and I want to hug you so bad right now. You're so special to me please come back." I spoke to her about it, and asked her who is that girl to her. She said "Haha just a really close friend." Is she telling me the truth? Is this something friendly that girls do or say? Or could it be something more?

hi From what you put it does sound like something is going on and she’s not being honest with you. Girls who are really good friends don’t send each other pics of or are that physical with one (holding hands, sitting on each other’s Laps) another unless there is more going on and they’re attracted to one another. Theses are kinda things that couples do...At least I’ve personally never done any of the above with a girl friend unless it was a hug in, as in not seen them for ages or comfort (if they were upset or something), I think you know somethings going on and isn’t quite right don’t get used or end up being hurt, discuss it with her again, and don’t just ask her and give her an easy way out.

Girls do cuddle and stuff but it seems there is more going on her. I think you should ask her straight out what the story is.
