disappointed. it's long but read. my grandpa isn't happy I'm pregnant.

I have a huge family and once my grandmother got sick with cancer ( I love my grandma so much! She was like the grandma of grandma's lol but I'm sure everyone feels that way about their grandmother) my grandfather asked me to come and help out with her being that she was in hospice care and basically about to die. Of course I moved in to help and there was arguments amongst the family because I was going to school and working a full time job and helping my grandma and nobody was doing anything to help me with my grandpa. there are FIVE children and NINE grandchildren everyone was basically trying to ignore it as if it wasn't happening. I eventually stopped trying to get them to care and just did what I could for my grandma until she passed because nobody else was doing anything to help. When my grandma passed in 2015 I stayed with my grandpa to help him because he's diabetic and he has glaucoma and also needs a lot of help too, I felt bad just leaving him after he had lost his wife of over 30 years so I've been here helping him, giving him insulin and making meals, washing his clothes etc, I love my grandpa and my family period but again it's the same thing with nobody else stepping up but me (maybe because I live here they just automatically assume that everything is taken care of but I'm not a robot.) still I'm here helping him etc so I mentioned to my grandpa about a month ago I said "hey you know you're about to have another great grandchild right" and he said to me "I'm not thinking about no great grandchild right now" and I said oh okay cool just wanted to let you know. For Mother's Day he called two of my older cousins (two of his grandchildren who don't even come see him btw) and was so excited to tell them happy Mother's Day but didn't say anything to me..so I said okay whatever.  Then today my aunt came and said "hey girl when is the babyshower" and basically just talking to my cousin and I about it and my cousin said he wants to plan it so i said to my grandpa jokingly "hey grandpa you helping out with my babyshower too?" And he responded "I don't give a damn about no damn baby" so I was like wow... okay ! So I'm a little disappointed because I've always been here to help my grandfather, I make sure he needs for nothing. He even cries sometimes and tells me his children and other grandchildren don't care about him and I try to make him happy etc and even tell them how he feels and have gotten into a few arguments but for him not to be happy for me makes me really upset. My cousin tells me well you basically do everything for him so with a baby coming he might feel like you won't do as much for him. But my thing is I've been doing so much for everyone my whole life and I'm only 24! I'm ready to give my all to my baby because I know that my child will love me unconditionally and I've always wanted to be a mother. He has FIVE children alive and kicking if you can be happy for your other grandchildren why not me?  Please tell me what you think I should do or how you would feel, because again I'm disappointed. I'm at a point in life where I'm like you know what whatever. I can't force anyone to be happy for me. What do you ladies think?
