Beyond upset

So we told my mom about 4 weeks ago. We surprised her with a folder full of quilt and sheet designs that I thought it would be a fun bonding thing we could do. I thought it would be great for her grandchild to curl up in bed with a special crate his Grammy would make for him/her. I also added a sweet and heart felt letter. She just took the folder and tossed it on her bed and said do you really think it's the best time. We were heart broken. My own mother. I was going to surprise my dad with a onesies that said "papas little trucker". (My parents are divorced and my mom is still pissed) so one day she got pissed at him because his new wife went to the office so in spite of him she shot out your daughter is pregnant. He's supportive but how can a mother do that to her child? This was my special moment to tell my family that we were expecting a baby.  She has yet to talk to me and yet to apologize to me. Ugh she's one to hold gruydgrs but I want my child to know his gramy even though she can be a bitch...
