Not sure what to make of these from a tailor? Am I overthinking this?

Long sorry short, I found and went to a local 5 -star rated tailor to alter a blazer and coat I’m selling. If it helps, he is young maybe up to 30 ish and Middle Eastern I think. I’ve been 3 times and overall he did a good job. Due to a mistake I made, I need to reline the sleeves a 2nd time and he kindly suggested to order the fabric for me. I agreed for the total quoted price of £50. He operates along in a basement level type place under a suit shop.

Up till now, he has been friendly and professional. We communicate/updates through WhatsApp. He does have a casual communication style in general.

Just over a week ago, I got these:

“??” at 01:01am Missed voice call at 01:33am “??” at 01:37am “Baby” at 01:37am

It did throw me off and Im unsure how to take this? Like what else could calling me “baby” mean? Is he flirting? I’m totally NOT used to anything like this over the phone and need perspective !

He messaged me again 2 days after that with “Hi” “Are you okay”. I have not responded to these. Him texting me this again 2 days after makes me doubt it was accidental?

Am I overreacting thinking this is just weird? I’m getting a bit anxious awkward to ask him directly as I need to ask him whether he has ordered the fabric and to not order it just yet :|

Just wouldn’t expect this from a 5 star rated tailoring service.
