I would gladly give them to her, but I fear it could have a negative effect to what little friendship we have
And she is married with kids, so while I will always like her, there is no hidden agenda on my part here.
There is no friendship between mand and woman.
Even under this axiom, giving such an amount of money to a woman, married or not, is inevitably change the balance of your "friendship".
Bad idea.
Don't.
