Dear fellow artists, please share your opinions with me.

I've met this girl last saturday on my sisters party. The girl is with a guy and they're already living
together. However, her boyfriend wasn't on the party because he wanted to watch the soccer match on television at home. Clearly, their relationship isn't really inspiring anymore and she definitely is in for some excitement. The girl hardly knew anybody besides my sister and as my sister was pretty busy with all the other guests, she hung around a bit lonely so I started a conversation. Pretty much immediately she started sending IOI's till the point my brother in law mentioned that 'You're playing a damn thigh game here mate right under your families nose and nobody notices! This friend of your sister, she wants you so badly she must be as wet as the sea.'

Point is, as the whole house was packed with people who knew either her, me or both I couldn't close the deal right there. I'm in a relationship (open, but my family doesn't know that) and she ofcouse couldn't openly kiss or anything because of all the people who knew her boyfriend. So in the end I #-closed.

Now she started texting me on Sunday and we're texting quite much and agreed to drink something when I'm
in town again (I live about 150 miles from her so I can't meet her sooner then the 1st of june, which is 1,5 week from now. Now she starts hinting to sex texting from time to time, and she also mentions that she wants to know me better. Worst of all, she once mentioned 'I thought you were up for some dirty talk but now you seem too well behaved for that'. Clearly she tries to lure me out of my comfort zone. For now I can joke myself out of those situations but I don't know if I can keep frustrating her this way for the next 10 days without losing her.

I don't feel it's the right way to join her in sextalk as I think she then just gets the attention she wants
and returns to her boyfriend. And after all, it's not what I want, I want to f-close her. And even if that
doesn't happen, talking about sex increases the pressure of our future date, as she will become more and
more aware that she's very probably gonna end up in bed with me.

Any ideas on this one?

My first thought is to stop or at least strongly reduce the texting, but that would be weird to do so suddenly
and it would perhaps even require a reboot to get her warmed up again next week.

I think my best strategy is to reduce tell her something more about myself to increase our connection (although this has to be done carefully too as I don't want her to get any feelings, I don't want to cause a breakup with her bf) and then reduce the texting while telling her it is because I'm extremely busy with my job (which is true, 60 hours next week).This way I hope I can leave her on a high note and then get back to her more easily when date time is there.

What do you guys think? Admit the sexual tension or cool things down for a while?
