Is it stupid to divorce your husband because of your mil

if you ask me, I don't think divorce is the best option here because the issue here is with your MIL and not really on your husband tho he is not supportive like you mentioned. I don't think the marriage should end because of another person tho I know it is hard to cut her off totally. I understand how you feel because some of the things you mentioned here were said by my MIL, quoting the breastfeeding example. I rmbr when my baby pooped a greenish poop she kinda questioned me what did I eat and she even control what I eat if she was around because she don't want me to pass to baby since I'm expressing milk. there was once I drank a packet drink and she nagged cuz she say so sweet later baby has phlegm how. same when baby is crying she will take over and if baby stop crying she will say aiyo your mommy carry you, you cry ah why ah.. which annoys me alottttt.. I suggest reducing contact with her to lessen the friction.. if you're staying together, perhaps try to move out? then maybe make it like occasional visits. Trust me when you lessen the times you see each other, you will find it less irritating.. I used to find her okay before giving birth but after baby is born she keeps coming over so much there is more friction. Separately, talk to your husband about how you feel and how you wished he can stand up for you.. sometimes it's not that they are not supportive, they are also in a difficult position too.. like my hubs so I try to stand in their shoes as well.. nowadays I just disregard whatever comment she makes if it is senseless.. I'll just give a smile and go away. hope things get better for you soon!!
