she's 22.

not all there either, her life is a bit of a sad story but her schooling ended one week into yr 7. and she spent the next 9 years locking herself in her room. socially dysfunctional and suffering from depression.

trust me that when i say that i gave her a good deal of chances and tried to help her. i had enough of her crap, her domestic lashing out/refusing to let me go home (as in stand in the doorway and i'd have to drag her away) and in the end i couldnt deal with her and my own problems and depression.

she accuses me of treating her like a dog but any other man would have dropped her and split as soon as she shown her true colours!
Josh, I don't know anything about you but I think the women in here have given you some good advice about the possibility of your ex not being pregnant.

I have serious concerns for your Ex and the way she is being portrayed in this forum.

As Taffy Lou pointed out and you have confirmed, she sounds like a disturbed young woman with many problems we can't begin to understand. Based on the information you have provided and your description of the incident with her mother also indicates there may be problems in her own home. This is a real person that may be crying out for help and while her method of doing so may seem unpalatable to some, she is clearly disturbed and she needs help. So Josh, if you are able and willing, could you ring a free counselling service and see if they have any professional advice for what may be available to help her. If you can't do it perhaps talk to someone who knows her who may be willing to take on some responsibility to help her. The ramifications if someone doesn't help her (to ultimately help herself) could be fatal or if it goes on, an innocent child could be born into a very unhappy situation.
