Is NOBODY wrong in the post ? POST : I (26/m) met Amanda (19/f) about a week and a half ago. While speaking with Amanda, she reveals that she is unhappy with her boyfriend (27/m) and has been for 6 of the 8 months they have been together. I told her that's ridiculous and if she has been unhappy for so long she should end it. She asks for my snapchat and we continued talking there.

We continued speaking via snapchat the entire weekend and it becomes increasingly more flirty. we discuss the dynamic of a dom/sub relationship and what turns us on about bondage and s&amp;m.

she made plans to come to my house, I'd help her with her homework, she'd be my rope bunny, and she wanted to "wrestle". I asked what BF thought and she said he doesn't care.

She was my rope bunny and then she suggested that we wrestle, but really she meant she wanted me to dom her brat. I spanked the shit out of her and she loved it. I asked her "what will you tell BF about the welts on your ass?" She said "I'll think of something." 

I say wrestling made me want to kiss. She said she did not want that. 

After geology homework, she prods me to wrestle more. I wasnt up for it.  she took a dog collar and tried to cuff me. I told her, "if you close the buckle, I will kiss you." She got really close to closing it and paused. after a few seconds I pulled them off. We cuddled on the couch but she had to go home. 

Next day after work she asks me what to do. I invite her over but do not suggest an activity.

She arrives, we hang out with my dog for a min before she suggests we head upstairs. she suggests I rig her in a pentagram chest harness.

We wrestled more but I became aroused and wished to take a break. 

She tried to cuff me and I say "if you do that, something bad will happen" She asked "you're not going to sexually assault me are you?" I say "spanking people will get you in trouble with HR. What's sexual assault defined as?"

She said "spanking me isn't assault, I drove all the way out here."

She then hit me with the end of her lead trying to get a rise out of me. I said stop, she kept on doing it. even demanded that I count them out loud. 

I said "I'll count them in my head, and if I get to ten, You will not like it." When she got to 9, I reminded her. She says she needs to go home, it's getting late. just before we started to get up she hit me with the lead again and got to 10.

I pinned her down and gave her a peck on the lips. She pulled away, but I telegraphed it and thought it was part of the game we'd been playing for the past 2 days. She didn't use the safeword. 

We walked to her car and hugged goodbye. She texted me until she fell asleep. 

Today she told me she doesn't want to hang out one on one again for now. I asked her what she thought would happen and she said "idk, not that". I told her I'm happy to be friends but no more wrestling or ropes until she dumps BF. 

Tl;dr girl with boyfriend sends severely mixed signals and is surprised when I kiss her. AITA?
