Considering the way she got pregnant was to honey trap the father! They have one child already (but are not together) and she decided it wasn't fair that she didnt have a brother or sister so she got drunk to sleep with him but planned it so she was ovulating - obviously he knows nothing about her wicked plan.
I have a family function coming up and have told her I dont want it to be subject of converstaion (as totally embarrassed), AIBU????
