Uncle D, I am sure you already know this in your head, but not yet in your heart, but this goes much deeper than your girlfriend not being able to handle you having a son. This all might sound harsh, but I am not trying to be, just trying to show you what I see as an outsider, and it might help you to hear this from someone who is objective.

Your first relationship was never healthy to begin with, the back and forth leaving for another man showed plainly that she did not love you. Taking her back each time, marrying her and bringing a child into the world together, were not good decisions. You apparently already know that, but now have to make the best of it and make sure that your son does not suffer for it.

Your leaving your wife for another woman... I think what is happening here is that your insecurity and low self esteem is taking over your life and your decisions are being made based on those emotions rather than thinking with your head and heart.

It is very rare that a relationship that began based on lies and broken vows will make it. And that is what you have with your girlfriend. She watched you lie to the woman you were married to, can you be trusted to not do the same thing to her if you meet another woman. These are probably things she is thinking.

There are plenty of women out there who are willing and able to love and marry a man that has children, and this takes a strong woman who is willing to share you with a whole part of your life that was before her. I married a man with two boys from two previous marriages, and it isn't easy by any means! And I wasn't the other woman. She has to be willing to make a lot of sacrifices, and be very understanding and this is made even more difficult by her being the other woman. You and she put her in a very difficult position. She needs to consider very strongly if this is the best decision for herself and you need to consider if this is the best for you and for your son.

But the biggest thing here, is that it is VERY difficult to love someone who does not love and cherish themselves. I personally think it would be best for you to let the relationship go and work on yourself and get your life together. Once you are financially stable, have your own place, that will help you feel somewhat better about yourself, but also some therapy would be a good start to get yourself to a position where you can have a relationship that is healthy and honest.
