No need to be Politically Correct with me! I am a WASP male, so therefore I am the cause of all evil in the world today! At least thats what the media tells me!! LOL
Anyway, you do not even want to think about having kids with this woman. Its hard enough being married, with both parents having no addictions, to raise a child. It would not be fair to the child to bring them into the world in an unstable relationship. And yes, fetal alcohol syndrom is a very real possibility.
You can not control your GF's drinking or her choices. But you can control yours. Do not have sex without protection. You cannot trust or depend upon her to take birth control. Alcoholics lie, thats what they do!
Since you are not married, you may need to face a tough decision. Continue this relationship, or move on and find someone else. Life with an addict is no life. You are young, but life is short...........you deserve to be happy!
