Parents

Please tell me your honest opinions I need some advice. I am 26 years old with a 1 year old and expecting June 10th with my second. My family act like around everyone that they do so much for my fiance and I. My mom acts like she loves my son so much but I know deep down she doesn't she just doesn't want other people to see she could care less or be bothered. I had my son last February 2015 and I swear they have seen him 20x total and have taken hin only 1 night. My mom didn't want to through me a baby shower I didn't want the gifts at all I just wanted people around me I didn't want to be alone. She couldn't even do that one thing for me with my first child. I can't explain everything I don't know if I am just over emotional or being dramatic but I feel like they do not care about my son or fiance. Most mom's are around to help at least a little bit my mom literally could not be bothered. I haven't talked to them in a couple of weeks and every day I keep getting mo4e qnd more mad. I am going to tell them I do not want them there for the delivery of the baby or after and that I don't want them around my son or in his life at all anymore. I don't want them to hurt my kids like they hurt me. I don't want them to d2el lik3 they did something wrong and that's why they never want to be around them. Please tell m3 am I over reacting.
