I agree with alot of what Briggsy's girl has said. While its dissapointed you that he has let the secret slip to his mum, he probably felt like he needed to talk to someone about it. Its hard for us females ttc when our bodies are controlling the majority of the process, and we tend to forget about how our partner is feeling about it all. In a way its nice to have someone special like your mum or MIL knowing about it, as then they know the extra special effort you guys have had to go to, to have a child and to provide them with grandbabies. Also I dont know what your MIL is like, but it may be nice for you to have someone else rather than just your DH to talk to about the whole process. I can understand your feelings totally but remember both you & DH need as much support as you can get.
