The only thing i can tell you is that you are probably grieving her absence right now. You're probably used to contacting her andhaving her in your life so it is normal for you to seek that old comfort.

Your life will be different now without her, you'll have to learn to adjust to her absence and then fill that absence with something else, but I do realize that some people are unable to do this. We can't all be the same. Parents never get over the loss of their child usually. I mean I don't want to see you get stuck in this, so, i guess, just focus on the other people in your life right now to try to fill the void.

She will always be with you, in your heart and it might sound like i am speaking about her as if she is dead, and in a way she is.

Don't be too hard on yourself during this time. Do try to fight the urge to contact her. Breakups are hard, divorces are one of the most stressful things that adults have to deal with.
