Hola.Im from Spain myself.I didnt fall preg on a nitestand but i have a girl from here who fell preg after one nitestand with an english man.What did she do? well..first, she never bothered to call him whatsoever,its easier if you can deal on your own.She has a 6 y-o child and she has these things in mind to say:
-If you plan not to contact him then tell him he's dead: so efficient.
-You can also tell your child he left, or he disappeared.
I have issues with my babys dad, hes my neighbour but dont want him to be involved,if he shows up ill tell my child the whole truth( he was the 1 to blame and left us alone during the 9 months) and if things are fine ill move on, ill tell my child her father just left us for some1 else.Dont worry for it!!!believe me, you are lucky!!
