Don't make her a mum if you're not ready for marriage. Taking care of a child is sure more expensive than a wedding dress.
Stop persuading her to have sex with you, if you love her -you'll wait till when you're ready to at least give her a wedding certificate.
This is what happens when you have no standard. Our standard is in Christ Jesus our saviour.
If you allow yourself to be fooled into sex & pregnancy before
marriage? It will be your turn to run after him. Soon he'll see another
girl with no responsibility of childcare!
