Can’t send texts to one specific number

TIMSMI65

Can't send texts to my Girlfriend, she can't send texts to me.

earlier we couldn't call each other either but we both reset our phones and deleted and made new contacts for each other.

I have sms and mms enabled and also tried contacting other people who have androids (works perfectly fine via text and call.)

We didn't accidentally block each other either. I've tried everything I've found on the internet (disabling iMessage) I'm at a loss here
