I'll start off with an introduction. I live in Israel, 22 years old. Haven't fapped in 5 years. Until last weekend, I didn't have any sexual interaction for 6 months. I stopped caring about sex, I did have the slight frustration of not getting any but I didn't actively look for it and couldn't care less. I'd even deescalate potential hookups sometimes.

Also, as a side note, I've been training up my Kegel muscles for around 4-5 months.

Last Friday, I hooked up with a girl at the bars, we got really hot really fast (45 minutes after meeting her we're already out of the bars), I made her cum and then she sucked me off. It was the most intense orgasm I've ever had in my life, probably because of the Kegel muscle training I've been doing.

For the whole interaction, I've been talking to her as if she's my "bitch", my property (in a playful way), she really liked it and we were both excited to keep it going after that Friday. We exchanged phones, I sent myself a message from her phone saying "Hey, I'm really into you" as a conversation opener from her side.

After Friday, we started talking a bit on Whatsapp, then we set to meet at Tuesday. Half an hour before we meet she texts me she's tried as hell and really sorry she can't make it today, and she tells me let's do tomorrow. I wasn't too easy about it, just told her that tomorrow (Wednesday) I'll have maybe a few hours free.

Open Wednesday. 5 minutes before we have to meet up she flakes again. I don't like that so I just don't answer her message. Today (Thursday), she messages me asking if I'm going to the bars. Can't make it so told her maybe some other time.

It's a bit long, I know, but basically, I feel like I've become slightly more emotionally invested than I should be. My classic game is just going out to the bars, having as much fun as I can, dancing and stuff. But since Friday my hormones have been going crazy (haven't had any kind of sexual interaction for 6 months before) and everything is scrambled in my head.

Now I feel like I've become a bit too much outcome dependent and I just want to go back to "chill, couldn't care less" me, going out to the bars to have fun. I'm going out to the bars tomorrow and am slightly afraid I'll become too outcome dependent if I get sex or not.

What should I be doing? How can I change my mindset? I want to go with a very healthy mindset to the bars tomorrow, not outcome dependent, but my hormones are going crazy compared to before because now I've just found out how awesome sex is again.

TL;DR: Haven't had any sexual interaction for 6 months, then had some at the bars and hormones have been going crazy since. Became slightly invested in the girl, want to rid myself of that feeling and just keep doing same me, without any outcome dependence. What now?
