Dear Unfaithful: Wow, lots of wrong decisions here. I know that I should reflexively pat your hand because you feel so bad and this is such a mess, but feeling guilty about your behavior does not absolve you from the consequences of that behavior. You had choices to make all the way along, but — unlike the guy you’ve been sleeping with — your infidelity has now yielded a lifelong consequence, the burden of which falls almost completely on you. (I assume that you will be keeping this baby.)
