We all are trying to help you but it does not seem like you want to hear the truth, does not sound like you want to actually receive our help. You know why. You have been given good advice. Yet, you have not listened to any of it.
You NEED TO LEAVE HER ALONE RIGHT NOW. Calling her and being overbearing and smoothering her to do what you want, like Janine has said will only make your situation worst. It does sound like you are way over top emotionally and that the way your behaving the way your acting towards her will make her more determined to stay away from you.
Please read everything that was written by J9,
alkalineangel and myself and look at your part in this relationship failing also know when to cut your losses. Right now is a good time. That means get back to work, that means contact her doctors, that means get ready to get paternity testing done after she has the baby.
Now you need to sit back, relax, and learn how to become patient. If you do not do this you will not be good to anybody. Take care of yourself right now and only focus on getting yourself well.
Now because of all of the back and forth and your emotional state. I think it is time that you see a doctor, and counsel. There is no shame in asking for help. You need to realise that most of the pain your feeling is being afflicted on yourself by your own thoughts and feelings. Once you realize this you will be able to make decisions that actually make a better future instead of being the opposite.
Best wishes.
Joe
