The first time she apologized I playfully brushed it off and told her I'm the bad texter and not her. I didn't think anything of it but then she apologized again.

I only text her when I feel like it and she definitely texts me more than I text her ( asking about my day, etc). I respond and carry on with my day.

I'm assuming she is low key trying to communicate to me that we should text more often without directly asking/telling me.

Obviously I'm comfortable with how much I text her and I'm not going to change that.

Any advice on the how to address this?
