Girls, I'm sorry but this is going to be another long one. I haven't talked to anyone about my MIL problems since they began so this is like a huge tangled ball of yarn that's been bouncing around in my head for months... and I need to get it unravelled now before I go insane.
Thanks so much for helping me through this... I don't really have anyone else to talk to about this, as I'm still trying to maintain some level of civility and not "tarnish" MIL's reputation to the family and friends I'd desperately like to talk to about this.
lyre, MIL is ramping up her behaviour again so she's making it very hard to take the high road. I'm dreading the holidays because her behaviour becomes more exaggerated when we spend time w/ family and friends who don't normally see DS. It's almost like she wants to mark her territory and feels threatened by others taking DS's attention away from her. If I give her the benefit of the doubt, it's because she's proud of him and wants to show him off... but I don't like how she snatches him from me to show him around, does not let anyone else hold him, and acts as if she knows him better than me, his own mother!!
tasha, I SOOO wish it was my parents who were behaving this way so that I could comfortably disagree with them and tell them off if needed to.
I know that there is this invisible "line" that should not be crossed between DILs and MILs but despite MY best efforts, MIL keeps overstepping HER bounds as a grandmother and MIL, putting me in a very awkward position.
I want to take your approach, mommyof3co. In fact, if I was dealing w/ a rational, sane MIL, how I'd fix this situation is to sit down and have a mature, adult talk with her, telling her honestly what bothered me and asking her to please change her behaviour as it is causing me a lot of stress. Frustratingly, she is very "bipolar", as better2gether so aptly noticed. She also seems to thrive on conflict (arguing w/ family members is almost like a hobby to her) so her default reaction to most conversations is to take the defensive and immediately become hostile. Add to the mix that her English isn't very good. If I were to try to talk things out with her, she'd be IMMEDIATELY offended and just create her own completely inaccurate understanding of what I was trying to say (she's already done this to me many times, in reaction to more mundane conversations). I'm sure she'd think I was being extremely disrespectful and ungrateful for the help she's given me.
better2gether: sorry to hear you're already experiencing MIL issues in pregnancy! Sheesh! You hit the nail on the head, what you said about bottling things up. I HAVE been bottling things up since she started up again because I've been trying to stick to the high road for my DH's sake (he asked me to try it "his way" for a while). But I was telling DH last night how this is creating lots of pent up resentment and anger. I admitted to him that I've been indirectly "punishing" MIL because she makes me dislike her so much. I've been very resistant to including her in special occasions like taking my DS to see X-Mas lights. I refuse to let her do his bedtime routine as I cherish that quiet, precious time w/ him. I make excuses to not go to dinners/lunches w/ her. I don't bring him over to her place to visit. If she wants to see him, she comes over here... but that brings me to another thing that pisses me off.
Lunaty: She just did the EXACT same thing to me yesterday!! She's done this since the birth... just shows up when she pleases... AT THE DOOR. No phone call, no making prior arrangements to come. She just SHOWS UP. To make things worse, she has a key so even if I don't answer the door, she still comes right in. In the early days, she often came in calling LOUDLY for me as she came in while I was desperately trying to squeeze in a nap for myself as DS napped.

I was FUMING last night as I tossed and turned in bed, thinking about it!
ARGH!!! I want to go on and on and get this all out but this is getting too long. Gals, if you can give me any support, I'm all ears... I do not want to end up in another nervous breakdown.
