I feel ignored

This is a repost I didn’t have an idea that I was supposed to provide a TL; DR

I feel ignored

hi I am male (16) and my girl is female (17) and we have been in a relationship for about 5 months now and recently I’ve started to feel ignored

I’ll tell you about last night. So apparently she had her class till like 12am from 10:30 onwards but then afterwards.In the mean time I sent her a couple texts after she was done i knew that she’d be tired so i respected the fact that she’ll take some to rest which is fair.
But then I started getting notifications on discord on my phone I have the access to her acc i never check any texts because that is a breach of trust and privacy but I couldn’t ignore the notifs.

She was talking to a person she had met the same day (she tends to reach out to new people from the servers she’s a part of) so i realised that she was available to text. So I texted her and she sent me a couple VMS replying to the vms I had sent the previous day and said that she’ll go for dinner. I listened to the vms replied with one of my own that was unrelated to what she sent and then I replied to her’s on text so those were two sets of texts she hadn’t replied to yet. She’s back again replies to a few texts goes offline again I was waiting for her I ever told her that as I was replying to her VMS and atp it had been an hour. So I asked if she was studying she’s said that she indeed was

But at the same time i was recieving the discord notifs and she was engaged in an enthusiastic conversation with the new person so I texted her asking if she wanted to say goodnight for the night and if she’ll listen to my VM tonight I had given up hope on my texts. She replied half an hour later about how she was feeling bad because she had “missed” my texts and was talking to another person andthen reassured me that the priority was me. That is fine I don’t mind it she can talk to whoever she wants and replying to me isn’t an obligation but atleast she should’ve let me know so that I wouldn’t have waited for so long and that too was the time I took out of studying for my test Tommorow and even now it’s afternoon and she’s had still not replied and I’m still reviewing her texts of having a conversation with the discord person at this point I’m just feeling hurt

I expressed it in another vm but she can’t hear me rn

What do i do

TL;DR

she tends to ignore my texts prioritising talking to someone she met the same day but also feels bad after doing that? I don’t get it and I’m not sure what to do,I love her to death and I don’t want this to go this direction
