The Dreadful Title of Weekend Dad

Week end dad- I don't want you to think that everything in my life is miserable. It just comes off that way as I'm venting. I have a wonderful family and a girl who I'm going to spend the rest of my life with. My baby girl is 6 months old and always puts a smile on my face. My son is almost 10 and I can't believe how fast he's growing up! Since he was 3 I became the weekend dad because his mom took a metaphorical shit all over me and the courts might as well applauded her.
My week goes like this as a weekend dad- The week is pretty much filled with anxiety throughout but Mon and Tue are pretty calm as long as I get to talk to him on the phone which has been less and less lately. Wed my stress starts to amp up. I always have to "check in" with his mom to make sure he's going to be at school on Fri so I can pick him up. (if you knew her track record you'd understand why I have to check in with her.) Thu. I prepare myself for the hour and a half ride on 3 hours of sleep (due to work) that I have to take on Fri to get him. Fri is getting him home and "fixing" him up. Somehow his Mom forgets to have him keep up with daily living skills for him during the week. Soon as he's ready for bed, I crash. Sat we can actually enjoy ourselves as a family. Sun, we both know he has to go home later in the day and we both get pretty bummed out about it. I drop him off. The guilt starts and the anxiety cycle is right back to where it started. You know what though? I'd do whatever it takes to see my little man!
