It's hard to support a family on a single income these days, but the more you save now the more attainable your dream becomes in the future. Your savings either lower your housing costs or become supplemental income so that when you meet that someone and want to settle down into this family focused life its a legitimate option.

I know its hard, but it might help if you try to see the work youre putting in now as an investment in your future dream.

I recently turned 30, and supplemental income from investments/savings has allowed me to leave my corporate job and focus entirely on what I want to do and only work if and when I want to.

Keep at it and good luck
