Who should I bring this to ? MIL SIL or none

I have been married for a decade and was quiet for quiet a long time on all the partialities, taunts, cunningness etc from MIL and SIL. For the last 2 years , I have reached my limit mainly because my husband has started to get too much lovey dovey with inlaws and is even planning to move them in.

In my last post, lot of you guys mentioned that I shall be quiet and not say much to husband . He does know how his mother, sister treats us but ignores it and his love for them is always the same. I take a back seat. He has gone to the level where he wants me to treat his mother sister the same as mine and it breaks my heart that i'm so left behind in all the communications from inlaws, but when it comes to my things I should be the same to my family or his.

My biggest problem is that if they are going to move in, I cannot live with all this . hence, for the past couple of years I have started to say more which seems like a complain to my husband, but yes that is a true situation that happened, you may call it a complain or whatever , but if eyes are closed I have to bring it up

Now the recent thing: When I got pregnant few months back and I told my MIL the same time as my mom My MIL immediately called my SIL and told her the news of Pregnancy .

This time my SIL got pregant, My MIL knew the whole time, but never mentioned a word to me. SIL tells me now . I congratulated her etc. But I feel why cant my MIL treat us the same. It is a good family news. We talk to her few times a week and both MIL or FIL never mentioned. They will ask about my pregnancy but never mentioned a word. It hurts me that SIL is like a family who need to be told everything immediately, but we are like outsiders who will be told when everyone else is .

I casually mentioned to my husband and he said ofcourse the MIL would have known from long, she must be waiting for SIL to tell. The thought never came to his mind, that the MIL did not wait for me to tell SIL about the pregancy . The news flew like a spacecraft and reached SIL . Also the hiding part ticks me off. The parent hiding stuff from one kid but to other they are like family .

I was thinking I should have a conversation with MIL and shall mention or request her to treat us the same. We dnt treat them any less parents that my SIL. Ratheer when it comes to doing anything financially, emotionally and even for their old age, we are responsible. so this treatment does hurt and effect the future .

what shall I do ? Any thoughts ?
