Hello
I'm not sure what I am going to say here but I will try.
First of all, has she gone through with the abortion or is she still contemplating? Truly, it is a hard decision and one that I would never have wanted to even go through. She's probably very scared to go in either direction and that may be what has turned her from you at this time.
She's young and obviously wants to fulfill her dreams to go to university. Now a pregnancy has made her face a big decision in life and she is now having to go over her priorities.
Another thing is, if she does abort she will go through guilt and regret, and that may in fact be magnified by staying with you and remembering her decision.
Truly, I don't know exactly what has gone on and I don't know the dynamics of your relationship. But, I suggest you give her her space and not smother her at this time. Sure, make sure she knows that if she needs anything she can come to you. But do not call everyday...wait a few days or more before calling her again. Let her get through what she is dealing with right now. Smothering isn't going to help matters.
As the saying goes:
If you love her
Let her go
If she comes back
She's yours
If she doesn't
She never was.
Best wishes to you. I hope it all turns out!
