well, i dont know if your story is true or not but i guess we should learn from other ppl`s mistake.
first, didnt finish study due to financial problem. second, you make other girl pregnant...third, you con ppl.
if you can see, one problem...coz another problem...and another..... i must remind myself, how lucky i am not being in your situation.

So, try your very best to settle all your debt. I dont see further studies is your solution right now not before you settle all the debts.
work first, even though its hard. BTW, u said you studied before...in what field and what is your qualification? about your wife, from now on....what ever you feel, how tough and hard your life is...you must take care of your wife and son. Dont punish them for the mistake you did...

wish you all the best...

p/s: i dont like conman..i got con twice so i really hate them!
