He stopped calling me babe?

Me and this guy have been talking for 2 weeks. After 1 week, I was just being nice and called him hun. He said “Aw you called me hun” then the next morning I woke up to a text saying “I hope you slept well babe” then for almost a week we were calling eachother babe. Now he hasn’t called me babe or hun. Should I be worried that I don’t have his attention anymore and it’s going elsewhere? We still text every day he still initially starts the conversation every day. And we are still planning on our first date after he recovers from his surgery (he was in a bad car accident). He wants to wait until he gets his first paycheck after returning to work to be able to pay everything during the date. He wants to be a gentleman. We barely ever talk about sex. We actually used to be best friends in high school, our first job was at the same place. We used to buy eachother Christmas gifts etc. Haven’t talked in years now we are friends again but working On a potential relationship.
