Keep treating her right and you'll start seeing those 4-digit CLI's soon enough.
Noticing the cards in your signature though it looks like you're stuck in low limit territory for some reason unless you first opened your first card 4/2019 then you're doing pretty well w/o any other experience.
A key component to making things grow is to use them monthly so the computers see use and payments.... this is why the fee based predator cards work for building scores. I like to just put a monthly bill on them and let autopay take care of it each month. The small monthly charge on one card took it from $4500 to $50K, another from 10K to 50K, and another from 10K to 65K. Minor spend on each of them and timing CLI's was key to growth. Total 1 year spend under 5K with additional use other than the monthly bill. It doesn't take much other than showing activity monthly and asking for CLI's regularly.
