Kathy...welcome. I too am going through the "NIGHTMARE" It isn't fun, easy or even comprehensible. Not one bit of this makes sense and from the women who are here to support you...they will all tell you, "you cannot make sense over something that doesn't make sense."
You are fortunate that your husband has contact with your son. That is a good thing. It took me 2 1/2 months to realize that nothing I could say, how many times I apologized (over something, anything, whatever) Just letting my DS and DIL know I love them and thinking about them, blah, blah, blah...it all was ignored and made me feel worse. It took this long for me to realize and understand it has very little to do with me. This is all about them and the more I begged, graveled and cried....it got me nowhere. Now, after all the support from the wonderful ladies here, some close family and friends...I realized all this and am able to sit back and say to myself, "I didn't do anything to deserve this and I don't want someone in my life who is treating me so poorly." I want my DS, DIL and GD in my life....surely...but not like this. I don't want to have the disrespect, the lies, the game playing, the two face behavior, the silent treatment when they don't get their way....That's not what a good mom and grandmother deserves. My other children don't treat me that way. I cried for 2 1/2 months and lost that much of my life and took the ME out of my other family members lives because I was so hurt by this. You need to understand that this is NOT about YOU! It's hard, so hard, the hardest thing I ever had to go through. I had cancer and still do...trying to get through this and the stress isn't helping me. I too had my DS and DIL tell me I whine or complain and they are sick of my drama...How dare them...How dare they not give me love, support and comfort. How dare your DS and DIL make that list for you too. Hold your head up. Deep Breaths...Believe me....Worrying, crying, all of that wasted energy got me know where....My DH's line, "How's that working for you?" He's right...it doesn't. LOVE YOURSELF!!!
