Peer influence is a big factor. If her friends or the people around her were smokers, she might have felt pressured to try it to be part of the group.
Maybe there would be the feeling of coughing a lot at first. Because the smoke is irritating to the throat.
In 'her' first cigarette story, it could be that she was in a difficult situation in her life. She might have been stressed or feeling a bit lost. Smoking a cigarette seemed like a way to relax or numb those feelings. She may have watched others do it and thought it would help her. So, she bought her first pack, took out one cigarette, and as she smoked it, she entered into a new, and not so healthy, chapter of her life.
Well, it could include where it happened. For example, it might be in a secluded corner of the schoolyard. Also, the reason for trying it, like if it was because of friends daring you.
She might be feeling guilty and wants to come clean. The guilt could be eating her up inside, and she believes honesty is the best way to start dealing with the situation.
One possible reason could be lack of communication in the relationship. If the couple doesn't talk enough, one partner might seek connection elsewhere. For example, if the husband is always busy at work and doesn't listen to his wife's feelings, she may be more likely to be attracted to someone who does. Another reason could be a change in personal interests. Maybe one partner develops new hobbies and meets new people through that, and those new relationships might lead to a situation where the other partner feels like a cuckold.
Lack of information could be a reason. For instance, if it's a new diet plan, she may not understand how it works or if it's healthy. So, she'll be reluctant until she gets all the facts.
One reason could be for comical purposes. It can create a really funny situation that lightens the mood in the relationship. Just like in the story where the wife crossdresses as her husband to surprise him when he comes home.
She may feel guilty. The weight of her unfaithful act has been too much for her to bear, so she decides to confess.
There could be a change in her own perception. Maybe she initially misremembered or misinterpreted certain events, and after further reflection, she realizes her story was inaccurate. Also, external pressures like social stigma or the fear of being ostracized can make her change her story.
Boredom can be a factor. If her relationship has become stagnant, with the same routine day in and day out. She might find someone new who brings a sense of adventure and novelty into her life, like suggesting new places to go or new hobbies to try. Maybe she meets someone at a new class she decided to take to break the monotony of her life.
