I’ve tried to communicate, but nothing changed

I’m in my 1st serious relationship and I need advice on how to handle this situation- am I overreacting/is it me/is it normal for guys to behave the way my boyfriend does?

We’re both 19 and have been dating for about 4 months. Since it’s my 1st relationship, I’ve been trying to do everything right- I pay attention to details about his life, always support and help him whenever he needs it, etc. I also 100% respect the time he spends with his friends because I know it’s important for him, I don’t wanna be controlling and demand from him to only spend time with me.

For the first few months he was really attentive, texted/called me to make sure I was ok, also paid attention to the thing happening in my life- completely reciprocated the feelings.

But now it seems like he doesn’t care nearly as much anymore- we don’t see each other as often, he can go an entire day without replying. I DID TELL/COMMUNICATE to him about how it made me feel, how I’m used to communicate more with the ones I care about, how I understand that we’re both busy and I would just appreciate a simple “i’m doing ok”/“i’m with my friends, everything’s ok” reply/text once in a while.

He completely agreed, explained that he doesn’t have enough free time for us to meet as often (I’m also busy with work, have my own life/friends so I UNDERSTAND how it is, BUT I still think it’s not that hard to check up on each other, even if it’s just a small text).

I’ve been completely understanding, have been working more, trying to distract myself with other tasks and just waited for him to “be free/have time for us to hang out”... Well this is the 3rd evening in a row when he hung out with his friends without even texting me... And I’m like ...??? Like I literally haven’t been pushing him, wasn’t a controlling gf who wants to be a complete priority... I just wanted to finally see him and spend some quality time together..?😂

Am I in the wrong here? Is it really too much to ask for? I’ve tried to communicate/talk openly about it, but he just doesn’t seem to understand..

I’m literally crying rn because I try to be a good gf as much as possible, but it seems like he doesn’t give a shit...

I would really appreciate any advice and hope you’re all doing good..❤️
