Hi Emma Lou my daughter's best friend found herself in much the same position as you do now. Let me tell you she now has the most adorable little girl who is nearly 2, you'll find that family and friends will rally round and help, there's a lot of support out there for you, just make sure you take it. As for Daddy - it's his loss, he may come to his senses at some point, just make sure he takes some responsibility for his child. You will not be doing this on your own, you'll find you are much stronger than you think.
I wish you all that's good, please when you have time let us know how you get on ..... boy? girl? xx
