Let me just start by apologizing for the lenthyness of this post. I just need some advise as to whether or not I'm doing the right thing. Starting at the age of 9 my step father started molesting me almost every night. No one knew or ever found out. So the day I turned 18 I moved out (I'm 25 now) and got my own apartment. I still came around to see my mom and sister who is 10 years younger than me all the time. When my sister turned 9 a couple of years later I told my mom so if it hadn't already happened to her she could prevent it and get away from the abuse. My mom immediately called everyone she could think of to tell them what had happened and moved herself and my sister in with me. The next day we went to the police station and filed a report. After 3 days went by she decided she would just kick him out of their house and they would move back in. She then told me we were going to drop the case because she needed him to pay her bills. Then a couple months later she tells me she still wants him to come around to see my sister because he didn't do anything to her, but she said it wouldn't ever be when I'm around. Then probably almost a year later I found out that her and my step dad are still sleeping together but "not really together". At this point I'm furious and call her out on it and she says it was just a mistake that happened a couple times but it wasn't really wrong because they are technically still married. So at this point I don't care about seeing my mom anymore and I just come around for my sister. Well 2 years later (I'm now 23)my husband and I adopted our nephew who was only 6 months at the time. My mom was great to him so I let her start coming around more. Fast forward to the issue today... My son is now 3 and I dont feel comfortable with my mom being involved in his life anymore. Despite everything she has done in the past, now she is letting my 16 year old sister see a 30 year old man "as friends" (which they are out until 4 in the morning sometimes), give herself tattoos ( she bought her a tattoo gun), and buys her cigarettes ( because it helps her with stress). I just don't want my son around them and think that it is a normal life style. So for the past 2 months I have cut out all contact with them. My mom keeps calling and texting saying she prays I never have to deal with the things she has had to deal with. And it makes me feel horrible...am I doing the right thing by keeping our distance?
