If you were dating a woman like this, what would you think?

Say, you have been dating a bit by visiting each other’s cities that are about a 3 hour car ride away from each other. You know that her son has been quite sick and she has expressed all sorts of worry and grief about it and you feel really bad for her because she goes on and on about being a single mother with no help. You plan on going to see her and her son for a week, but instead of her looking after her sick son, she sends the boy away for the week so she can spend time with you alone, and then you find out she didn’t look after him the week prior either and nor does she have plans to look after the boy the next weekend either. Would you find her insincere?

(yes, perhaps I am just looking to justify my feelings about a situation, so could you all just bare with me and help me trash this person a bit?)
