Cancer woman Capricorn man

We met online, had a lot in common,and hit it off very well. Had a few dates and dinner. To both of our busy schedules and her kids we don't have much time to see you face-to-face but we text and chat daily.
Things were going fine think he had any issue with the custody of her children and kind of stop texting me .
whenever I text her she will respond sometimes if hours later. But I don't want to seem like I'm being too pushy but on the other hand I don't want to seem like I'm being a cold Capricorn and not supporting her and her time of.
Any advice?

I agree, she has a lot on her plate. But sometimes she does not return text or phone calls to make initial contact . I don't feel like I'm adding more pressure to her life or barking up the wrong tree
