funny secrets

so my bf and I have to dogs and we call them the girls. we live together as well and I've mentioned to him that I tell them little heartfelt secrets and it's a little teasing game we have. I mentioned today that I have another secret I've told the girls and he wants to know lol. I told him I'll tell him Sunday when he gets home. the secret is I hope we get engaged soon is that too forward or am I over thinking?
