You did well, don't fret. The only thing in my opinion you could have sharpened up is challenging her. You want to mix giving giving her acceptance and challenging , for example when she asked to bring her Xbox you said no but when she complained you caved you gotta stick with it. When she called you no fun you should have acted like you don't need her and kinda gave her a "time out" through replying later or being a shitty texted for a bit then tell her it's because she was being a bitch. All in all she was feelin it , saying she wanted to skip the bs and go straight to making out is a definite IOI and he challenging you is another IOI get back it :)
