Help!!!!!

I'm expecting my first child in August, Yeahhhh! My DH is 28, I am 20. We courted for for 2 years, became a couple when I turned 18, married at 19. We live together on our own but, for the sake of arguments we often visit his family(the In-Laws) for the weekend.


Because of my age, my MIL doesn't respect as a woman muchless a mom. She believes that I have to experience things in order to be a mother. She's partially right but, still it kind of disrespectful telling a pregnant woman she's not a mom.


Anyways, this weekend past I watched her breakdown the manhood of my husband & demeaning him in front of me (she slapping him). Over him not feeding HER dogs on time. I intervened by telling him to take a walk & she turns around, aggressively replying "shut the F up"


When all was said n' done, after watching my husband cry they make-up but, the problem comes into play when she called to for me to ask "Why don't you listen to me?" All I thought was this woman has a lot of nerve to expect me to answer to her. She constantly says "You're not a mom" & "You're not as grown as you think you are". She also feels that I look bothered when I'm around her, I need to tell her my whereabout & I should depend on her as far as taking care of the baby goes.


I don't firmly voice my feelings-opinions to her because I feel she is extremely hostil. When the baby is born I do plan on laying down the rules.


Is my timing off? Should I cut her off?


Generally I feel like she is upset about the relationship I have with her son. I deny help from her only in preparation for this baby because it seems as though she wants to control my life. She wants me to be dependent on her and, feels that it's rude when I respectfully decline.
