My ex husband is constantly letting my children down with empty promises. I'm always left picking up the peices and dealing with their upset . My daughter aged 13 seems to handle it better by not expecting the promises to happen , yet my 16 year old son is different. His dad lets him down, yet he forgives (and rightly so) , until the next time etc etc. But when he gets excited about a promised event, and I try to give him advice such as 'be careful about getting too excited in case it doesn't happen etc' I get accused of bad mouthing his dad. How can I give advice without it seeming like I'm slating his dad? This is not a new scenario as we've been divorced 9 years.
