Just make sure you don't say something like "You seem to be really busy at work these days, since you haven't been answering my texts right away. How are things going with the new job?" That will only come across as "fishing" (about OW) and insecurity . . . blcccch, UNATTRACTIVE.
Instead just a simple "So how's the new job going for you? Is it what you thought it would be?" or something similar.
