My mum passed away when I was 13, my dog brought me so much love and comfort, she really made me heal (she got me through the teen years!) and she is absolutely my world. I have been very good friends with someone for a while now and we began dating, he knew I had a dog and it was fine, but we have been speaking about moving in together and he says he couldn't live with a dog due to his allergies mixed with asthma, I knew he had asthma, but he never said anything about his allergies. My dog is now 11 and is expected to live 12-15, he says that I have given her a good life and I feel like he is trying to get me to get rid of her 
that would never happen, but it's sad he thinks that's okay, she is getting older now and really needs me. My aunt who I am quite close to has said that he could be the one, which I agree, he very much is, I love him a hell of a lot. It's so hard. I have said that we don't need to move in with each other right now, but he says we are at that stage in the relationship. He says the only choice would be for him or the dog to not be there, as it would make him to ill. I wouldn't be unreasonable to pick my dog would I??
