Hopes Dreams and Realities

Things took a very differnet turn today. As much as thing have improved between me and A, I knew he was being...distant from me. I didn't know why and didn't want to press it. I hoped he would tell me in time. I knew he was going through a nasty custody battle with his ex over their son. I knew this was likely the reason behind his recent irrational behaviour. I was overjoyed today to learn that he won the custody suit. His son is 100% his, no strings, no BS. His son is where he belongs, with A, his loving father.
This in no means prepared me for what he said next. He asked me if I would be willing to move in with him, and help him raise his son. I was stunned. He is willing to share his son, his pride and joy, with me. There is an awful lot to think about, and even more to do before I can hope to render a decision on this. I need to consider my wants and needs, A's wants and needs, and most importantly, his young son's needs.Would this be best for him? Would I make a good second father figure for him? I must admit if i could make the decision now, had the means to cut ties here and just go with no repercussions, I'd be writing this from a beach in Tampa, but alas I'm not so lucky. What of my career that I've worked hard for? I'm nearly 3 years into a 5-6 year commitment to become an electrician. Would my current Canadian training carry over in the States or would I be required to start over, and could I even start over, is there even work? If I can't find a job in my field, what would I do? Would they even allow me to live there if I had no job prospects? All things to consider, and yet such a small part of the big picture.
I know that I love A with all my heart. He is a great man who has shovelled shit all his life, but never complained because he knew it just had to be done. He confessed tonite that he has had deep feelings for me for a very long time, but due to his conflicts with his inner demons, he has been unable to express those feelings until now. I also have very deep feelings for him. We live in different countries, yet are even closer then I am with my closest friends in my own city. We talk every day, sometimes more then once. We have a neat set up that lets us watch baseball together using the net. We know who the other is, what kind of person they are, their strengths and faults. This wouldnt be like some mail order BS. We do have a emotional connection that is strong, and I think will only get stronger now that our feelings are out in the open.
However, is this right for A's son? I have no answer to that. I have to rely on A to know what is in the best interests of his son, and apparently he thinks that I am. I am no stranger to child care. I routinely babysat for relatives since i am the oldest in the family by nearly a decade. I am certified, with CPR and first aid. I can cook anything a kid would ever need to eat. I'm not really worried that way.
Also, what impact could this have on my family? I'm not out to my mom and her husband, or my siblings. My father and his wife know and im fairly sure that my siblings have an idea, but still. This would need to be dealt with before I could ever hope of leaving. I'm planning on coming out to my mom next week once i'm done school, but I'm not going to mention this until I know how she will react. How will my father react? He's moving out of the city for a job in a nother province with his wife, but I have no doubt he will be concerned about my wellbeing. A has said there is no rush, that i need to discuss ths with everyone I can. He said he will wait for me, as long as it takes. That is a true commitment, I am worried though that I will either make the wrong decision for myself, or for them, or that I will not be able to uproot myself from here.
I am very, very happy, but I also am staring down a mountain that I need to climb. What lies on the other side I'm not sure.
