don't know whether I should give up

[luda]

Ok so let me give you some background information on my friendship with a girl named Rose. We know each other because of our social circle. Well I had sex with her friend and she had sex with mine. Lol its kind of fucked up but that's the situation. So I have told her some sexual things like I want to fuck her, eat her pussy and that I find her hot and she keeps saying its not gonna happen and stuff. Haha funny enough we still friends and talk pretty often

Here is an excerpt of a conversation we where having yesterday on bbm. Where she was asking me why I said I like her boobs in front a guy she was vibing with:

Her:No, but u ddnt have to say it right infront of him
Me:Haha ok I guess I was wrong there... So... Rose I like ur boobs
Her:What's so nice abt them?
Me:Lol when I explain u gonna call me a pervert after
Her:No I won't! I'm curious!
Me:Haha ok.. Uhm they look firm, u know big but not too big, lol they make me wanna squeeze, lick nd bang em
Her:Lmao!!!! U such a perve!. Wanna bang? I told u that ul neva bang me!
Me:Hahaha I know but hey I just can't stop hitting on you.. so just allow me to hav a lil fun
Her:Y can't u stop?
Me:Lol I don't know hey.. Its who I am I guess. Lol don't take it too seriously
Her:Lol. U won't give up?
Me:Haha ok.. I have given up though
Her:why??
Me:Lol.. I thought that's what u want
Her:it is...

So that's usually the feel of our conversations. I say something sexual and she resists it. I don't know if I should just give up or keep trying. Any advice would be helpfull and really appreciated
