Quoting ×ø×K·ßear×ø×:" maybe because they already had their children and they dont want to raise more? you are young, still in school, and have no job so obviously it would have to be them to take care of it."
It is not a puppy dog, that kid will be with you for life. I think abortion would be the best option long term for you. It may sound tough now, but you will thank them when you are walking across that stage getting your diploma and go straight to the graduation parties without having to worry about your 5 year old at home. Trust me.
There is always time for babies once you are stable and out on your own. Now isnt the time.
