Sometime back, when I was pregnant with my second one, I expected MIL to do some evening snacks for me as I came home famished every day. Not once did she check on me whether I needed something, even when I was vomiting profusely. I was distraught and was feeling helpless, angry, and disgusted. I kept thinking how great it would have been if girls could stay with their parents rather than PILs. Actually, it's the girl who needs more emotional and physical support than a guy, even on a normal day. But none of these thoughts helped me. I conveyed my thoughts to my husband. He informed his mom and fought with her sometimes, but I did not get what I wanted. She started making vadas, bajjiyas with lots of oil or the same 'adai dosa' every single day. Oh god! That nauseated me and made me vomit even more... My Husband started getting irritated when I did not have more than 3 of those oil ladened vadas at a time. I felt programming a computer was much easier! Helplessness and anger were pushing me into a dark negative pit, making me more emotional, cranky, and unhappy. I wish I could go back in time and keep smiling all through my pregnancy rather than being grumpy and overthinking. Alas! it's too late now. I immediately started a thread on IL and got a different perspective altogether. In IL, rather than telling the harsh truth, the wise ladies here tell us how to navigate through the present situation diplomatically. Just like how India averts a war with China or Pakistan every single time diplomatically. Does this mean we, Indians, are nut heads? No, it means we value the peace and prosperity of our country and people more than anything else. I sometimes felt the girls here in IL were pointing at me, but no, that was not what they intended to do. They are actually screaming out loud through their replies to give priority to ourselves and our mental health even if the sailing is not so smooth. I completely understand your situation and empathize with you. She is not entitled to know about your periods, but at the same time, you also don't have to let her know about your periods through your husband. Statistically speaking, most of the PILs don't care much about their DILs, just like how DILs don't care about the PILs. We do stuffs for them out of compulsion rather than out of love for each other, most of the times, for the sake of the person whom we love, our husband. So, it's ok if they don't care about us. But being civil, respectful, and polite is very important. But you should care about yourself, so to avoid conflicts and be smart, you just have to ask your MIL to cook for you if you are a little unwell. or If you can't cook for them, you can inform them beforehand that you will be unable to cook for them as you are unwell. Husbands are very bad at communicating things to their parents. They don't even know how painful periods are and what thoughts go inside a girl's mind during periods. We have to do it not because they are entitled but because we need our mind space to do something productive rather than ruminating about a conflict.
