No Acknowledgement of Pregnancy from Family??

So I know I'm probably super hormonal at the moment but I just wanted some of you other mama's to be weigh in. My relationship with my family is slightly strained and we choose to love each other from a distance. Long story short, they don't like my stepfather and didn't agree with hil moving on after my mom passed away from Ovarian Cancer 4 years ago. Although our relationship wasn't perfect, my stepdad has been in my life for 20 years and it was very important to my mom that I continued to involve him in my life. He has changed and grown. Anyway, I announced our pregnancy, which mind you is my first, after being in a terrible car accident on my way home from work. I was traumatized and terrified and in so much pain I was sure that we were gonna lose the baby. However after having an ultrasound and seeing the little heart beating away I was so overjoyed and thankful that God spared us both that I decided it was time to share the news and give thanks for my blessings. Not one person in my mom's family or my Dad (biological)'s family has acknowledged our good news or congratulated us.... I feel like this is extremely hurtful from people who claim they love me. My aunts and my mom were best friends so I thought they would be happy for her daughter. My husband has told me on numerous occasions I should cut ties with them because he doesn't believe they truly care about me or have my best interests at heart. I was only 22 when I lost my mom and she never got to meet my husband. She passed away a few months before my college graduation, and obviously has missed many important steps in my life such as getting married and now having my first child. This is a very difficult time for me and I miss her so much. Through these times my family never once stood by my side and only added uneccesary stress.... Do you think this is something that merits being upset over? Does any one have any experience or advice? Thanks for the support in advance.
