So the cartoon you saw in the paper pictured a sneaky, angry looking mother-in-law. She was pointing her finger at her son-in-law and accusing him of driving a wedge between herself and her daughter, according to the caption, and the huge chunk of wedge held in the hand of the poor son-in-law.
I am concerned that the paper printed such a cartoon. For what purpose? Probably to make a caricature of mothers-in-law. Someone said that we tend to argue, not with things as they really are, but with things as we imagine them to be. Basically, a cartoon shows a dilemma as we imagine it to be, not as it really is.
So, if you are thinking that you, as a mother-in-law, could behave in a similar fashion as the cartoonish woman, forget it. From reading your email, my guess is that you have your head on straight and you love your family, all of it. Carry on.
