Things are tough

Well my flight was great and now I am at mom's house. I'm very aggravated with my ex husband. He won't let me have my kids like we planned,and I just don't know what to do. I am meeting them at the park at 3:30 so I have to just accept things for what they are.I will still enjoy the time I have with my babies.I'm just struggling with the fact that I'm doing all that I can, and he is treating me this way.It's not fair to my kids.I hope the rest of the trip will end well.
