Love what the hell are you doing?
I mean kids there crazy. wait you silly girl, damn...... I just had a thought my best friend in having a child who is 19 and girlfriend 18 and im tottaly supportive so I guess saying that is kind of hypocritical.
But still its not right, I mean your ex could be a rocket scientest with the greatest brains, a big wallet and an awesome face but it still does not justify having a child. You say you want to be a single mum? Trust me its not cool, I have come from a single mum family and its hard, not just on kid but the mum also. My mother was always making sacrafises for us are you willing to pretty much give up everything for your child? to have it with someone who you cannot share it with?
Also its better if you find someone you want to be with because that kind of thing is best shared with someone, just wait im sure your bound to find someone from your picture your stunning, hit the clubs, places where people hang out there is bound to be a guy who you can like who is ready to have a child, and if he is not ready im sure your willing to find you will wait for him.
Damn this is long I hope you take this subject seriously, man I feel wise for someone who is 18
