Gabbi, if it makes you feel a bit better. I did not have what one might call "total moral support" from family in the beginning of my divorce, either. My mother said things like "No other man is going to want you with your having a child" which ofcourse was BS, and really only proved that she's still in the dark ages. My former in-laws were really awful about the whole thing, telling me that you just don't leave your husband for any reason. And there were lots of friends who chose not to "be there" because they didn't want to get stuck in the middle. It took my actually leaving and getting on my feet myself for several months before anyone, even my former in-laws, to recognise that I truly did the right thing. Even all the friends that didn't want to be caught in the middle returned with apologies.
I look back over the last 6 years of my life post-divorce....all the horrible struggles to survive and provide for myself and my son...all the hardships ... and realise its truly all been worth it because I would have struggled worse had I stayed with that person that continuously dragged me down and out. I would have missed out on so many experiences and opportunities.
Your father will eventually come around. People in our parents' age range were taught to stay married no matter what. I'm sure there were times throughout your parents' marriage, as with all marriages, that neither of them were perfect, too. You also have to see that neither of your parents have dealt with your situation, they've never lived it, and you're bringing this to them very suddenly without much warning. Give it time.
Stay strong, Elizabeth
