Sinead

You've been married to Sinead for about 15 years. Ten years ago, she cheated on you in an impulsive way, and she regretted it instantly. Somehow, you managed to forgive her, due in large part to her clearly remorseful response. She vowed to make sure that not a day goes by that you don't regret your decision to let her stay with you. And she's been true to her word, going overboard sometimes in her efforts to make you happy. That is, until about a week ago. Her attentiveness has been declining, and she's started to look distant. She's become jittery around you and has been coming home late from work. Each time, she's mumbled an apology when she comes in, but avoided eye contact.
