How to avoid catching feelings for a girl?

Recently I’ve started seeing this girl just as I started uni. We’ve been on a couple dates and each time we’ve slept together. Trying to avoid going down this route as when I’ve got the opportunity for regular sex and I’m consistently releasing I turn into half the man. Literally walk around with my head down and I’m super neurotic. Its awkward as well cus the girl is staying on the same floor as me in the same student accommodation. She’s very my much type and ive enjoyed the time we spent together. She seems keen for a relationship but i know that my discipline will go to shit and this has come just as I’m starting my first year of university/college where I’m going to need all the energy and vigour I can get so I can go to the gym, train MMA and do well with my studies. Also I just want the social skills that retention gives me as there’s loads of social opportunities which I don’t want to miss out on cus I’m fucking a girl and spending the days after hiding away from the world.

Feeling very conflicted right now

Hi Guys, I’m 20 years old and have just entered my first year of university (college in US) studying business management. Truthfully although I have struggled with confidence and still have days with bad self esteem, I’d consider myself an extrovert and a very pleasure seeking person. Hate to label myself but I’d say I have an addictive personality, I struggle with moderation. I was looking for advice to staying disciplined at uni, Im yet to start a gym as I’ve moved to a new city. I find No fap and meditation helps quite a lot but I struggle with the fear of missing out. There’s so many opportunities for sex and partying that it seems like it’s going to be difficult to stay focused on fitness, self improvement and my studies. Last two week have been freshers week and induction which is basically a week full of student events and then introducing us to the course. Haven’t missed any work yet or anything as there hasn’t been a lot of expectation but I’ve spent so much of my student loan.

Anybody who’s been through something similar care to offer some words of wisdom, would be greatly appreciated.

Thanks guys
