Well I'm new! But I'm in the same suituation! My BF of 11 yrs. has had an affair and it has to ended in the OW being pregnant, and he's stepping up to the plate and being there and I just don't know how to feel. I feel that I can't trust him and I don't believe anything he has to say. I'm really frustrated about the whole situation and I don't know what the hell to do. I talked to him and he said that he dosen't want the OW or the baby, but she said that regardless if he dosen't want the baby or not she's having it. Please help me to anybody!!!!!

Update
The OW met my BF Friday morning with proof of the pregnancy. She is 4 weeks along. He said the old feeling did not come back and has advised her he does not want to be with her.
She has agreed to an abortion, and she did not call us at all over the weekend. I am hoping that she has gotten the message. He told her if she decided to keep the baby she would have to deal with me for the next 18 years. I'm hoping she will come to her senses. I don't believe in abortions really but if she were to have it, the poor child would be very confused besides the fact that she is drinking and smoking now.
We still have a lot of work to do on our relationship.
I attended my first Al-Anon meeting Thursday. All of this started with his drinking. He has been attending AA meetings. He also has a split personality (runs in the family) and has an appointment with a doctor. This morning his 10-year old daughter has her first appointment with a counselor. I'm hoping this will all help.
Wish us luck.
