So I have raised my son from the age of 7 months with my partner. We are a same sex couple and his birth certificate mum left him at 6 months to move to Australia. He is now 2. She is now back from Australia and wants something to do with him. Everything I do is what’s in the best interest for him. But I can’t help feeling she’s now back in his life because she can’t stay out in Australia and I just don’t want him to be anyone’s second option. He deserves to be everyone’s first option. I have no parental rights at present to my son and she does. I don’t want my emotions to get in the way of what is best for him so just wanted abit of advice on other peoples thoughts on whether this is what’s best for him? I have turned my whole life around to do what’s best for my son and I would do anything for him, he is literally my world and it would destroy me to lose him but in the eyes of the law I am not his parent
