Advice from women?

So; I've recently been talking to this girl- we have really hit it off; we speak everyday and she hasn't missed a morning message in 4 months. Issue is, due to my past, I get quite anxious about things. (My ex cheated on me numerous times)

The main two are- every now and then I'll check our messages to see if my messages actually sent (I have dodgy Internet where I am sometimes) and it told me she was online x minutes ago. 90% of me knows this is nothing to worry about, but the other part is making stupid scenarios up like 'she's seen your message- just doesn't want to reply' or 'She's found someone else'

She has around 400 followers and follows 1000+. I think I'd get a big iffy if it was more 400 followers/50 following. I just worry there's someone else in her DMs.

It's not in a possessive way- I just like to know I'm the priority you know? We've both told each other we love each other pretty much daily; and she always reassures me.

Women on here- would you still follow back someone who requested to follow you? Would you loose feelings for someone if you've had a bad day?
