Will a girlfriend get in the way of the Marines

Hey I’m (18M) and a senior in highschool and I want to join the Marines. I’m attracted to a few girls at my school (17F-18F) who I all find attractive for different reasons and I don’t know if it’s a good idea to get with one of them since I’m enlisting after I graduate. If anything, a short-term relationship would be nice, but it would hurt a little bit to break a heart.

I’ve been in a long-distance relationship before and I hated how homesick it made me feel when I could’ve just enjoyed life with my friends instead of thinking about my girl over in college. I’m out of that relationship now but I’m afraid of repeating past mistakes. I’d imagine such a relationship would be much worse in a stressful environment like the military, let alone the Marine Corps.

What do y’all think is the best course of action for me to take? I’m curious what y’all think so I can understand other POVs and ultimately make a decision for myself.
