I want to write in English so he can read as well
I have been married to an American man for 15 years, trust me, if he tells you what he did is American way, he is taking advange of you as a foreigner.
He is nothing but a white trash. American people are indenpendent people, It is umimaginary to most of then to ask their parents money to buy house, do not even mention it is your parents, under circustance that you are not willing... It is also unimaginable for most of then to let you go through 3 abortions. I use the word "most", I mean I have never heard a story like this in the 18 years I have been in America.
Do not give yourself hardtime. Now you are experienced and I think you will take better care of yourself. No matter what, do not mess around with married man. If you do, more likely than not, their exs fate will fall on you.
