To deal with my ex. I know not many people are on good terms with their ex but mine drives me crazy! He declares undying love for our DS and blames me for not seeing him enough (not true) but every time I offer for him to have him or see him there's always an excuse 
To be fair, he does always pay for him but I think he sees that as him 'doing his bit' so no further effort is required. He doesn't really talk to me (about DS, I don't care what he does with his life any more) but I know he goes round telling everyone everything is my fault.
Anyone else with a nightmare ex who wants to share a rant or two and tips to help me deal with him?
