This girl in my friend group (we're both 22) and I have hooked up twice in the past week. Great fucking sex and whatnot.

I hit her up yesterday to meet up, but she said she had a migraine from drinking with the group and didn't eat anything all day. Asked to reschedule to tomorrow and I agreed.

Tonight comes, and I didn't text to confirm. Also, I want to note that our friend group is going kayaking tomorrow and I've been really looking forward to it since I've never been. Out of nowhere, she says "you're going to hate me." I ignore. She then said "I have to bring my grandfather to the hospital at 5 tomorrow and I literally just got out of work". I just said "understandable." She then said "I'm really sorry. Would you want to go watch the sunset after we all go kayaking tomorrow?" Again, I ignored. Five minutes pass, and she sends me a snapchat of her looking sexy. Opened, ignored. Two minutes later, she texts "OP, hellloooo?" Ignored. Five minutes later, she sends me a gif of a girl mad on her phone, with the caption "You can't ignore me!" and I ignored again.

So like I said, we're all going kayaking tomorrow and I have to see her. Her best friend is apart of the group and wants to fuck me bad (she never told her that we fucked since they've known each other since preschool and knows that it'll put a huge stain on their friendship), but I feel like fucking her friend would be petty as fuck.

How should I behave around her tommorow? Act like nothing happened or straight up act indifferent towards her? I can tell that ignoring her is driving her crazy and it's working. We planned to do a shroom trip tomorrow at a lake and fuck, but I'm not even going to bring that shit up. I have a feeling that tomorrow she'll say something like "so do you want to go see that sunset with me after this?" or some bullshit. She also asked me yesterday before she flaked if I wanted to be kayaking buddies with her, and I just said "Hmm.. maybe if you don't sink us". I don't know ifs she'll ask to partner up with me, and am pretty clueless to what I should do. If it was just our plans, I'd cancel last second like she did. Since it's the group's plans and I've been looking forward to it, I want to go.

Thoughts?
