she knows gopi is easily influenced by rashi n she also knows rashi is using her, she has also seen a change which to me is good in Aham but she is not wanting it she wants it on her terms gopi sit aham sit gopi stand aham stand. Even though goham will not succeed in getting raji together they will have become closer but the person that will no longer be in control will be kokila when she handed gopis education n minor matters to Aham she did it because she wanted to prove to her mother that her bahu was the adarsh bahu but now her mother knows that rashi is a cunning vixen for kokila its no longer a issue, time for nani to come back..
Remember what parag said in the cinema as a child aham would say he wants to go to cinema n she did not let him n she turned round i am happy i did otherwise he would not be the man in the position he is in now, she herself has some traits like rashi wanting power head of house etc in doing so we thought she created not a son but monster until now we see a loving caring thoughtful aham, but now kokila will be pulling the reins she is going to be splitting up goham i can see this coming due to her own unsecurities, but would'nt it be nice if gopi gets pregnant before that n Aham comes running back totally ignoring his mom.
