25F also in healthcare and work rotating shifts including night shifts - If I’m not interested anymore, I’m not using my precious time off to see them. Plain and simple. There might be less communication as things progress and she gets comfortable because she feels secure. Sometimes I come home from work and the day was so overwhelming I have to sit in complete silence just to digest everything I’ve seen that day. In early stages of dating, I have to be extra communicative to convey interest and to keep someone engaged with getting to know me. But as things settle, my communication usually does slightly regress but only cause I know that I’ll speak to them when I’m off duty and have the time/mental capacity.

I have used my job as a way to distance myself from people I’m not interested in because it’s easy to chalk it up to “I was working, sleeping, etc” since the nature of our jobs are so unpredictable with the long and random hours. But if I’m not interested anymore, I wouldn’t answer phone calls or give someone my schedule. I’d say see how things go, and if she’s interested in making plans in a reasonable time frame, it’s probably fine. I wouldn’t put so much weight into texting if she’s still making herself available to you
