Ok, here's the quick background story so you can understand what's happening.

I am 25. My parents got divorced when I was 3. My dad immediately started dating L, and they eventually got married 7 years later. My mom started dating F 5 years after the divorce and they got married 3 years later. Mom and F are now separated. Dad and L are still going strong. Mom and I have a strained relationship, mainly due to her psychological issues that have not been properly addressed. L and I have a really close relationship and she was always there for me when my mom couldn't be during many bouts with hospitalizations from a chronic illness.

Tired yet?

The gist of all of this is that my Mom despises L and blames her for the problems in her marriage to my dad. She still hasn't gotten over it 22 years later with over 20 years of therapy.

My mom has brought up twice since I've been pregnant that L doesn't "deserve" the designation of Grandma. She first tried to say that the boys will be confused with more than 2 grandmas. When I pointed out to her that my step-grandmas did not confuse me as a child, she relented and said "it's because of how she came to be in our lives." Mom thinks Dad cheated. I was 3. What do I know? and honestly - it's not my business nor my problem. That was their marriage and their relationship, not mine!

I told my mom that how Dad and L met is not going to be a bedtime story for our boys and that I don't believe that she (L) doesn't deserve the Grandma title. I also told her that I'm sorry she is STILL hurt but it really isn't my concern and nor will it be brought up to my boys. Period. I told her I don't want to talk about it again, because these conversations always turn into fights and I don't want to be stressed with these babies coming.

A couple hours later, she calls me back and says that she wants to be called Oma instead of Grandma, since L is going to be called Grandma (so is MIL). I told her fine, whatever, she can be called whatever she wants but that she's the only one making a big deal out of this.

I'm serious stressed about this because my Mom doesn't have the capacity to let this go. My mom is physically disabled and will not be able to babysit alone due to these disabilities (but she insists that she will be fine). She is also borders on hoarding in her home and my sons will not be going there at all (though she thinks her house is fine and the boys will be there frequently).

When I bring things up to her, I try to make it about the well-being of the boys (i.e. Mom, you won't be able to pick them up on your own because both of your shoulders have torn rotator cuffs and you can't lift a gallon of milk. We don't want any accidents for them or you.)

DH is getting mad because she constantly stresses me out and makes me cry, then tries to blame me and yells at me. I'm already anticipating issues at my baby shower (that L is throwing for me because my Mom can't physically/mentally handle doing it) and it's to the point that I don't want to go anymore.

I dread when the boys come because L and my MIL will be helping me with all the physical aspects of things and my Mom can't.

*I know I sound like an awful person. I understand that my mom was hurt, but honestly I'm so lucky that I had Dad and L in my life growing up because they gave me the stable home Mom couldn't provide - and she'll never see it that way.

I don't know what I'm looking for in the way of advice. I think I'm just looking for support. I don't want my boys to be damaged by the toxicity of my relationship with my mom. I am and have been in therapy for quite a while in regards to this, but it has escalated since I got pregnant.

(Please be gentle - I'm already super upset right now)
