Ok, I have read comments from certain people saying that they would stop hanging out with their friends because of a "weird" problem like this.
First, if you think a friend has a problem and your solution is to dump him/her, then you may want to reconsider calling that person your friend. Friends don't just abandon each other when things get rough. They see something they think is a problem and try to discuss it with said friend before deciding on any hasty paths.
Secondly, I put weird in quotation marks because this really isn't weird if you take the time to consider it. Let's take the trans women here as an example. We feel so bad about ourselves that we're willing to take hormones for life and go through serious surgery to feel more comfortable in our bodies. We deny being in the sex we we are biologically. Therefore, I don't think any trans person, myself included, has the right to call someone weird because he//she truly yearns to live the defining feature of his/her associated gender (for women, it doesn't get much more womanly than pregnancy). Doing this might mean a lot to her because she has intense gender identity issues. For all you know, she could be a little push away from an emotional breakdown.
Considering the age of this thread, I don't know if this person is still doing this or if you decided to follow up on your decision to dump her as a friend, but the above is just something to consider.
