Wow..This situation took a bad turn!
Ok, first ask yourself what do you want?? If you dont want an abortion then dont, and if ur parents force you, tell the doctor, coz the doctor probably wont do it coz the client is refusing to!
Second, I know it's so nice of nick's father to offer u guys so much, but, I think it's wise not to take the offer 100%, coz then u will be in his control (maybe not if he is just truly nice and wonderful), but if u do take his offer, but dont just do what he wants u to do, coz that's just like ur parents, so just do what you think it's good for you and the baby!!!
Third. If u r finanically capable, do pay nick's father rent or something, dont rely on him, I dont know, it's just me, I dont like depending on someone becoz then freedom is not totally yours anymore, it's just what I think though.
Forth, talk to nick, see what he thinks, if this guy cant think, darn!!! Eheh...But seriously have a talk with him and see what he thinks is good to do.
