Final Final Decision

I am very new to this site, but I am just desparate to communicate with people that are and have gone through the same things...

After yet another tearful discussion late into the night last night, we decided to go ahead with our plan to try insemination beginning in August. Although we both want to have a child, it has been a struggle to get to this point. My partner and I are very different is some ways, and this is one of them. We usually balance each other out, but it is hard to see her so upset about something that should be a joyous decision.
When I want to do something, I do it. I don't care about what others may think, or say, or do. I just care about what would make us happy, and that is all that matters to me. But she is a worrier. And this decision stresses her out.

Her worries:
Since the baby will be my egg and a donor's sperm, what if she doesn't feel connected to the baby?

Her family will never accept it as their grandchild.

Her grandparents do not even know that she is gay. She can hide me, but it's a lot harder to hide a baby. What if her grandparents get sick and have to move in with us? We were prepared for this as a couple, but how is she going to explain at that time why she has a child she has never told them about?

Money, of course, money. We make a good living, but I'm not sure she'd feel confident if we made 10x as much as we do.

We have a nice house, but it is in an area we wouldn't want to raise a child. What if we can't sell?

I'm getting older every day. I have no idea if I have any fertility problems, so I don't want to wait even longer to find out something is wrong. Not to mention, my eggs are getting older every day. I have a younger brother with Autism, the age thing really scares me.

Well, I am estatic that we are finally on our way in this journey, but I just wish I could help her with her fears. Some of the questions I can't even answer, but I just trust that the future will iron out the wrinkles.
