A woman texted my husband that she misses him?

Is he having an affair with her? She texted him late at night and told him she misses him (among other things) and he replied by saying I'll meet you day after tomorrow and then texted her the following day asking her if she'll come. I think this woman could be one of his clients (he's a fitness trainer) since I don't know her at all.

It sure sounds like an affair to me
