my boyfriend told me he will have a vasectomy reversal

My boyfriend had a vasectomy after his second child with his ex and was adamant about not wanting any more. When we first started dating I thought I was ok with not having children of my own. But as our relationship progressed and became more serious I realized I was not. I have been scared to talk to him about it and tell him my change of feelings. Then last night out of the blue he told me if I wanted a baby he would have a reversal so we could try. That he would be happy to have another child with me and to think about it for awhile. I'm not sure what changed his mind. But i'm super happy. We just bought a house together and now he has agreed to try to have a baby someday. :)
