<human>: Give me a shortened version of the text

In the past 6 months or so my Mum has said two particular things that have been very hurtful to me and she has admitted it's caused significant tension between us. 

1. My mum has always LOVED children and always made comments like "When am I going to get grandchildren!". I mentioned recently that I wasn't sure about having children and she replied something about how that was good, she was happy I might not want to. Upon further probing turns out she doesn't think that a gay couple can make adequate parents so it's better I don't have kids.

2. She has a policy that when any couple visits and they are unmarried, they can't stay in the same room. This is frustrating enough in itself but she also wasn't sure if I would be able to do even if I get married (once it's legal, I'm in Australia) because she wouldn't necessarily recognize the marriage. 
 
I have expressed how I feel to hear and bawled my eyes out etc. But eventually we decided we would just not talk about it as we weren't getting anywhere and it would only make me upset.

I don't feel like she understands why I find this upsetting, and I'm not sure how to get to a point where I can accept that she thinks this about me and whether I can get to the stage where we don't have his tension between us. 

I thought I might write her a letter explaining, but I'm not sure how to get it across or if that would even make any difference.

Would love some advice.
<bot>: Mum said she was glad I wasn't keen on having children and wouldn't recognize my marriage because I'm gay. Not sure how to proceed.
