I agree with Tone's and Ellynn's posts because they make a lot of sense. Yes i think some type of a break is definetelly needed here. I think you really need to reestablish the "friendship" part first before continuing with this particular relationship. Relate to her as a friend with no mentioning of the relationship component (Keep some mystery in there) and maybe soon enough she will get back to the girl you knew a month back.
Ellynn, your post makes so much sense that it scares me There are some girls i know who are guilty of that, changing their views, minds, hearts, souls, everything in light of a pregnancy scare. It's almost like the pregnancy scare is scarier than death itself, forcing the female character to abandon all logic and breking every single promise she ever made to her partner in order to just get away. I have seen this kind of behaviour in men as well, but lately it is becoming a lot more evident in women (Well, for me anyway), which really scares me because i always thought that women in general are a lot more responsible than that. I hope I am not over generalizing here.
Good Luck!!!
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
