Need some encouragement

Hey mommas , so heres my situation im 21 yrs old i have a two year old and im due with my second boy early October. Im trying to go back to school To get a degree in music education so i can give my children the life i feel they deserve. Problem is my  S/O keeps telling me im going to fail and that its pointless because im going to have this baby mid semester and according to him i can't attend any classes for 6 weeks. I wasnt planning on starting out with more then 3 or 4 classes and i was going to take as many as I could online but now im feeling really hopeless and i dont know how im supposed to succeed if my "main support " doesnt support me or have faith in me
