You have to be very very honest witrh yourself.
Can you offer this baby a decent life, feed clothe and house her until she is eighteen, including the emotional and physical support she will need?
If not, and your circumstances indicate that this will be difficult - then you should consider your options.
It's a shame that this baby was not conceived as part of a relationship - and despite you saying you love the father, he obviously fails to feel the same way about you.
You can consider adoption as another option, but i would suggest you speak to your GP who will refer you for some specialist counselling from people who can help you make this very very difficult choice.
