Hi. i dont know what kind of help i can be but if you want some advice from a different perspective, here it is. I know the type your talking about, the lieing, cant stand to be around kind. I have the same problem exsept im on the other side. Im married and my husband has a 5 year old that i just adore and his mother will not this child know his half sister or me. I know what its like. I dont see a reason to leave the woman out of the picture because the father dosent know how to tell the truth. I might sugest supervised visits for now untill you can get to know the woman better, you might be surprized as to how well it could go. And just remember that she isnt trying to take your place as his mother, no one can do that. Caleb will know who his mother is. You can still teach him ur christian beliefs as he grows, and strengthins his relationship with not only you and his father but with the other women. If it is the father that is telling her somthing different, i dont see why she wouldnt be allowed to spend a little time with the child with the father. Sounds like to me its the father you need to worry bout, not the woman. This is just my side, cause i know what its like to be on the other side. Talk to her, you never know.
