trying for un-interupted time with my DS

[EarthHippy]

I'm divorced from an abusive ex-husband. We've been seper. for over a year and divorced for several months. I feel good about moving on, and in many ways i have. I really moved on while we were separ. i had no intention getting back together with him. I'm still healing from his emotional abuse, verbal and sometime physical. He was also very controlling and isolated me from friends, and out of country family.  That's the long and short of it.   Now to get to my issue......

During our "joint custody" separation, we would each call our son to say goodnight every night while he was at the other parents house. This was to help reassure him, that i loved him and visa versa.  My son has transitioned threw this very well, it was a long step by step separation and divorce. This was not a hugs and kisses divorce, and my ex has done everything under and over the sun to make everything difficult for me.  he pushes buttons purposely. I have called the SS on him, for neglect of our child. He's like a 16 yr old in a 30 something body.  Any who, He still calls EVERYNIGHT at like 7 30 8pm to say goodnight, On my days with our son, we have joint custody, and when i get him on a Thurs my ex will just pop over Saturday night to "give our son a hug" then leave. its a 5 min to 10 min thing. the constant phone calls (i call 2 nights out of 7 when my Ex has him, and rarely go over to my ex house just because)  I would really like my time which is 7 days with out his dad interrupting dinner with calls, coming over at night. I really want to be left alone. Time with my family. We're not married anymore.  How can i heal and except my divorce if my ex is ALWAYS around??!  

How do i stop these calls, He'll leave hateful messages on my cell if i don't answer and then he'll call the house like 4 times in a row. You cant talk to him about this he'd bark at me telling me i cant keep him from our son..I'm so lost , and frustrated... How can i make this happen less????
