struggling w/ a relationship after a rough patch due to my bf’s shift work

so here’s my situation:

me (F20) & my bf (M22) have been dating for almost 4 months, we’ve been talking for 6. but we are going through a rough patch rn. everything was going perfect up until he started shift work in january. we just went on a break for 3 weeks (we did not break up, we just didn’t hang out and only texted each other) because we needed some space from each other. i was constantly irritable & just picking fights over the littlest shit that he didn’t deserve, on top of that he was constantly exhausted bc he was working 12 hour night shifts 2-5 days a week for the last 3 months, he is unable to see his boys as much as he used to due to his sleep schedule and working hours. no matter how much sleep he got he was always tired. i told him that those 3 weeks we will work on ourselves & do our own thing and start hanging out again in the month of april. he just started day shift which is why it was 3 weeks so he can finish out night shift & now i want to give it the next month to see if anything changes with our relationship during day shift. but i don’t know if i should just initiate a break up or wait to see if things change in our relationship. it was a mutual agreement to give each other a break & start hanging out again & he’s willing to try & hopefully save the relationship as much as i am. i genuinely see myself being with him in the long run, but maybe its a right person wrong time kind of thing?

TL;DR;: should we break up or give it a try? is this is a right person wrong time ordeal?
