I was 18 when I met him and moved in with him (same night :0 ), although very nearly 19.
20 when I married him - and 4 months pregnant. 21 when I had our second daughter, and 22 when I left him.
He has gone on to marry twice more (I was his second wife), has 5 daughters and an adopted son. My daughters are his second and third.
My choice of man at 18/19 was appallingly bad. (Obviously didn't think so at the time though.)
