Well, you can't blame the pregnancy ENTIRELY on yourself...
Your sitch is tough... but you two could move into houses or apartments next door to each other so your son could go back and forth at will. A friend of mine got a divorce and moved a block away from her ex. Her kids went freely back and forth between the houses. They were in grade school. Now both have graduated from college and live away from home. There ARE creative solutions. There was an article in our local paper about a happily married couple who live in an upstairs-downstairs duplex. She lives upstairs and he lives downstairs. Of course they spend a lot of time together, but they each love having their own space.
You can't take all the responsibility for a solution on your own shoulders. Also you can't live the rest of your life this way.
