The great dilemma....I don't want to have children?

In this economy. I'm afraid I won't be able to give them the best when they deserve it. My boyfriend and I have had a severe disagreement on this. As much as I really love him, I think this will end things between us. I'm extremely depressed. I don't want to leave him. Yet it's been an extremely rocky week. Probably the worst one. I feel horrible. I handled it very poorly as well.
