(18F) Missing BF (19M) now that life is getting busier, how to adjust?

Hi, I’ve (18F) been with my BF (19M) for about 2 years now and things have been getting busier between us two lately in terms of jobs and studying. I’m currently doing full time study and part time work whereas he is doing work full time, hybrid 9-5.

I’m used to hanging with him all the time and sleeping over. I understand it’s getting busier between the two of us and really, the only day we’ll be able to hang out properly is on a Sunday as I’m working the full day on a Saturday and he’s busy on my free Tuesday.

I’m worried that this might indicate some type of codependency as I’m so attached + accustomed to being around him so much that this feels super weird and ‘off’ to me.

I’m trying the best I can to get used to it so far but I’m already feeling so weird and uncomfortable and I think transitions always make me argue with him more and I’ve just been feeling so tired of everything lately. It makes me feel like just retreating from everyone and I feel rejected when my boyfriend says he doesn’t want to hang out on weekdays to focus on work, even if it’s just an unavoidable commitment. I just feel like maybe he’ll meet someone better and seeing each other just once a week is gonna make me feel sad even though I’ve been trying to meet up with friends and continue with my hobbies in my spare time and self care. It’s like I can’t take my mind off of him and it annoys me, because I just feel moody all the time.

Is there any advice/tips to help reframe my thinking or any similar stories to know I’m not alone in these adjustment periods? I feel so silly and I know having less time is anything that the more mature adult couples experience, however I’ll just miss seeing him around.

TLDR; My BF (19M) and I (18F) used to spend a lot of time together, but now we’re both super busy and only see each other once a week. I feel moody, miss him a lot, and worry I’m too attached or that the distance might hurt our relationship. Trying to cope but struggling—any advice?
