Hey..hey..slow down. The journey is the fun part...not the destination. You are on a very rocky path right now, and making hasty decisions is only going to hurt you and your child. I looked at some of your past posts, and noticed that at the end of October you weren't even dating...and now you are engaged to a man who basically fell off the face of the earth for a time, and didn't have enough respect to contact you. What's the big rush? If he is Mr Right, he doesn't need to be Mr. RIGHT NOW.
First, stop, take a deep breath. You DO NOT need a man to fulfill your life and help you escape. You need to take a step back and build a life for yourself and your child...possibly with this man...someday, or maybe not.
You need to find stable work and a good support network, be it friends, family, church, etc. People who want to see you suceed.
Moving...wait until you have a better grasp of your self and your life. Stop worrying about "being an adult" and "spreading your wings." You have some growing up to do, and throwing yourself into a marriage and a move is not going to do it in a healthy manner.
Buying a house? Wait until you are in a place that you are planning on remaining in for at least 3 years (just to cover your closing costs). Yes, you can buy a house cheaply...but if you do move again...you are going to be SELLING it cheaply, too. The last thing you want to do is lose a bunch of money just because it is a buyer's market, and you could have a lower monthly payment.
You need to start making some pragmatic changes in your life. Now would be a great time for you to find a fulfilling job...or go to school. Something to improve yourself so that if things with your move, your family, your boyfriend don't pan out - you have a saftey net...yourself.
Believe in yourself...then find yourself. Once you are where you need to be you will have the tools you need to swim instead of flail about trying not to drown.
The man part is easy, and if it is meant to be it will still be... a month, a year, or even a few years down the road. You need to focus on yourself and your life before you bring another dimension (man) into the equation.
Stop talking about moving, marrying, buying a house, and being mad at your parents, or your ex. Focus on bettering yourself, and in the process bettering your child...the rest will fall into place.
