Am I right or am i wrong?

My girlfriends friend informed her that i was in my class flirting and poking on another girl. Truthfully I wasn't. I remember all i did was say Hello and gave a hug but that's all. i mean she's my friend and im just being friendly. And my gf said okay i believe you. now she tells me, i dont feel comfortable with you talking to her anymore. she wants me to zero talk to her. I told her. she didnt do anything intentionally, nor did i. i say hi to the galfriends i have and give hugs. am i right here?
