RUN!!! Do NOT make this woman pregnant. Don't engage in any more of her games. You have a pension, medical benefits, access to BX and she has a vagina and plenty of access to additional penises. In the end, she will get what she wants and you could lose part of what you have. This is a dishonest relationship and frankly, I think she's a bit of a head case (and not in a good way). Sometimes its better to simply cut your losses and walk away. To me, this looks like one of those times.
