How do you know when a Cancer has lost interest in you?

Imma October Scorpio and I was dating a June cancer back in late 2024. We ended up breaking up cus she wasn’t ready to be in a relationship since she just got out of one before meeting me (he was abusive, she needs to heal) long story short we’ve hung out since then, went on “dates”. She’s done my hair for me before I had locs which I appreciate and she said she can give me a retwist soon but idk. Her energy has shifted and I’m noticing a pattern with her now that I don’t like. She’s not as reliable as she once was and she takes a minute to text back now. Should I just leave her alone? I don’t think she’s interested in being friends anymore. She could be busy, I thought if that. We were on the phone for an hour the other day and we talked and it was fine but I just have a feeling that I should move on. I don’t think she’s the type to be direct about not being interested anymore
