A married woman's willingness to date alone may represent several situations, depending on her attitude and behavior.
Friendship: She may just want to be on good terms with you, see you as a friend, and therefore be willing to go on a date alone with you and share each other's lives and feelings.
Affection: She may have a crush on you and is willing to build a deeper relationship with you. Dating alone allows her to get to know you better while also giving you a chance to get to know her.
Seek comfort: She may be experiencing some problems or difficulties and needs to seek comfort and support. Dating alone can make her feel more secure and relaxed because she can confide in you about her worries and concerns.
Infidelity: If her marital status is unstable or already conflicting, she may want to seek comfort or support, but that doesn't mean she'll be unfaithful to her marriage.
Whatever her intentions, dating alone is a sensitive subject. If you're confused or unsure about her intentions, it's best to communicate with her directly to understand her thoughts and feelings. At the same time, respect her wishes and decisions, and don't force her to do anything she doesn't want to do.
