Single and Pregnant.

I'm an currently 17 weeks pregnant at the age of 20 , And my BD broke up with me about 2 1/2 - 3 months. At first I was devastated. Crying every chance someone wasn't looking and extremely depressed. I have some what came to the conclusions that this is how things are going to be. However everytime I see a "pregnant couple" or think about the fact that me and my child's father are not wont be together I break down all over again. Out of all of the plans I had for my life; getting pregnant and not being married or even on the track of marriage was definitely not one of them. I'm think I'm more so hurt because my pregnancy isn't anything I ever would have pictured. So my question to you ladies is : how do or did you cope with this situation.?
