Comments from possibly jealous coworkers aside, be aware that both you and "Jason" are human beings, and as such just as liable to make relational mistakes as anyone else. You're both best served by being conscious of that, and proactively avoiding situations where either of you might be tempted to go beyond professional friendship. It's a slippery slope best avoided. Do I think you're likely to make such a mistake, even given the chance? Not necessarily. It's just that anything that risks your marriage, even a little, is simply not worth it.
