Yes I was surprised when the doctor actually came on even though I didn't ask to speak to her
This is almost laughable. So you call and say "Hi, I'd like an appointment for so-and-so" and BAM - the doctor is on the phone? Sure, that happens all the time.
I'm not saying it's impossible, but there are better odds of hitting powerball. Unless this doctor is OW's best friend, she's not going to instruct her staff to get her immediately if a male calls looking to set an appointment for a patient.
(an Indian Lady, her practice came up in multiple online searches. Based on what she said it sounds like she was expecting my call.
Just because her practice exists doesn't mean you were speaking with the doctor.
I think she was using me setting up the appointment as some kinda confirmation/proof that this is real. As I said I played along, but no money was going to be sent.
Setting up an appointment does NOT mean she's really pregnant.
In your shoes, I would absolutely demand not only proof of a pregnancy, but also proof of paternity before spending one more minute on this. The entire thing sounds just so far fetched and abnormal.
At 11 weeks, she wouldn't be showing. As Solus stated, anyone can make their stomach protrude a little. An 11 week old fetus is about the size of a lime. What exactly would be showing?
In many states here in the US, you can sue someone for the 'intentional infliction of emotional distress' and yes, lying to someone, telling them you are pregnant with their child when you are not, would qualify.
I don't think you're dealing with a pregnant woman. I think you're dealing with a bunny boiler.
I strongly recommend letting her know that you must have proof of the pregnancy before continuing any further discussions regarding this issue. If she acts offended again, calmly apologize for offending her, but there are legal and insurance issues that need to be addressed, and without hard proof your hands are tied. Remain calm no matter what the reaction.
Once you've done this, have no further discussions until solid, actual proof is provided. If she does not provide proof and also does not stop contacting you, I would state, calmly once again, that proof of a pregnancy is a very normal request. At this point, I would also, calmly, state that if she will not provide you the required validation, you are considering the matter closed and see no need for further contact. If she continues, calmly let her know that the intentional infliction of emotional distress is grounds for legal action, and if she persists you will have no alternative but to seek a legal remedy.
Always allow her toe opportunity to provide legitimate proof, but do not engage at all without it. Do NOT sign anything, do NOT claim any legal responsibility, simply put, do NOT engage. If she is lying about this pregnancy, she is most likely more than slightly unstable mentally.
So allow the opportunity to provide proof, but until such proof is provided, ending all contact is probably your absolute best bet.
Regarding your BGF, honesty is the best policy. If OW actually is pregnant, BGF needs to know. If OW is lying about being pregnant, she will most likely tell BGF about your relationship. Either way, BGF will almost certainly discover this, and it's best that she hear it from you imo.
You're in a very difficult situation, but right now you still have some control over how it unfolds for BGF. Soon enough, OW will possibly take that option away from you. As painful as this news may be for BGF, it could be made 10 times worse if it's conveyed to her by OW, particularly if OW is not getting what she wants - which is a family with you.
