lilma35, how are you feeling? I had a baby when I was only 17.
That ex of yours loves to put you through emotional tourcher doesnt he? Its going ot be hard but the best thing you can do is ignore him.
Having a baby is an emotional rollercoaster for any woman! Let alone someon who is going though a break up. You deserve better than he can offer you. You do what you feel is right when it comes to your baby.
At the end of the day it is you that will be looking after it, not your family. Bring up a child is not easy, but I wouldn't say it is that hard either. The first few months are, but then you learn how ot make things easier and you become an expert
I have a forum made entirely for pregnant woman and parents. If you would like to chat with other mums from all over the world gimme a shout and I will give you the link

I promise you there will be no judgement, no matter what you decide
Good luck xxx
