I can imagine how painful it is that you had all those years when your mum struggled to allow you to live your life, only to see a glimpse at the end of how it could have been if she’d been able to see things differently, earlier. She probably thought she was protecting you when actually she was lucky she didn’t push you away - and that’s down to your love and devotion for her.
Sweetie, I’m a Christian, I was raised in a Christian family. My husband is not, nor has any desire to even consider it. My daughter is gay. I love them both very, very much and nothing and no one will ever change that and I will never turn my back on them. What I’m trying to say is that there is a huge difference between true Christianity and religion and those ‘religious people’ you’ve come across are not Christian in my eyes
