what you said in the red is actually so disrespectful if you were to say that to your MIL. yet you are asking others on this forum for more suggestions?! don’t say that to your MIL.
your in-laws are your husband’s parents - you need to remember that they mean everything to your husband. if you have any respect for your husband then for his sake re-think your attitude regarding your in-laws. you owe them honour and respect esp’ as they will be coming to stay with you.
who knows - they might be feeling exactly the same about you and are worried about how you might treat them!!
how would you feel if your husband was to behave disrespectfully towards your parents? you’d be hurt! so don’t treat his parents any different than how you’d want your parents to be treated.
when your in-laws come, welcome them kindly and open-heartily. be polite and patient with them - if they say anything that you don’t like then bite your tongue and say nothing to them. it will do you no good to answer back to them.
