No one is trying to be critical; our apologies if it came off that way. Everyone here is extremely concerned for not just the baby that you'd like in your life, but also yourself.
Understanding or not, arnimal's advice was terrible. Browsing chat rooms is not safe nor is it logical. There have been numerous reports of people who got approved by adoption agencies but either had to wait or couldn't afford to adopt; they decided to "find" a surrogate mother on their own. They empty out their bank accounts buying anything and everything the surrogate could want or need; when it comes time to deliver, the surrogate takes off and the couple is left broke and empty-handed. They have no legal right to the child because biologically, it's not theirs.
Like you pointed out, give yourself a few years to get situated. You can rebuild your credit, show a steady rental history or even homeownership, a strong marriage... all of those will be beneficial in an adoption review. I wish you and your soon-to-be husband the best of luck :)
