Where to go from here

Ok, so long story kinda short... My mom was very manipulative, and verbally and emotionally abusive to me throughout my childhood and adulthood to be honest. Over 2 years ago I started setting boundaries and sticking up for myself. Since then our relationship has been rough because she resists the boundaries and calls me selfish, a bitch, and last time we spoke told me to go to hell. No she's not very nice, my husband does not like her and doesn't want her around our 18 month old. I get where he is coming from, but I miss her! I mean, I miss my mom. I miss having her, and talking to her. Most of all I am so upset that I am causing her to miss out on my beautiful son's life. We haven't spoken in 2 months. What do I do?
