Girlfriend is ignoring my texts

You are really reaching. You know people can have a day where they just haven't been on their phone?

She’s read the messages and been active sooo

Do you realise people are simply just busy and don't have time to reply to messages? Some might just read it and then when they have time, they'll reply.

You're overthinking it. Don't be *that* clingy boyfriend.

Not really clingy and she’s clearly not busy as she’s been active sooo

wow, i have no idea why everyone is roasting you, OP.
there's a few reasons why she might be ignoring you, so let's examine them...

1) she's busy
2) she's testing you
3) she's mad at you
4) she's lost interest

obviously, you know your gf and how she behaves. at least, i'm assuming you've been together long enough. which of those points listed above sounds likely to you? in any case, do NOT spam her inbox. that is how you come off as needy. even if you are needy, you don't want her to know that, so play it cool.

it's perfectly okay to be concerned. just leave her a question, ask her if she's okay. you don't want it to sound pushy or invasive, just something cool like "hey, is everything okay?"... keep it short. when she finally replies and you're in conversation, you can expand on your concerns, but never leave tons of messages outside of conversation.
