My Mother was exactly the same way. She had a gay brother (who ended up committing suicide), and she knew first hand what a hard life he had because he was gay. Mom has always had gay friends too, so she's always understood gay issues, and truly isn't homophobic in any way. She just wants the world for her children. I think once Mom realized after I came out that I was the same person I'd always been, and I don't take ANYBODY'S crap, much less somebody giving me shit about what I do in my bedroom, she calmed down. I also think my Mother saw how the world is quickly changing in regards to acceptance of gays.
Your Mom will come around... just give her time. She has to realize you won't be fitting into the box she's spent decades building, and once she cleans her slate, all will be well. For instance, I know my Mom has always loved the red hair I got from her, and loves my temperament and personality... and greatly wanted to see those attributes passed down to Grandchildren. It was a huge blow to her when she had to discard her hopes of Grandchildren. There are all sorts of expectations a parent has to change when their child comes out. It's just a readjustment period. Do your part to make the transition easy for your Mom, and try your best to softly educate her along the way. I guarantee after the dust settles, you'll have a closer relationship with your parent than ever. :smile:
