Being a working Mom

Over the past 4 months I have started working full time. I really enjoy my job and have loved getting back into the hospitality industry. I think it is just my nitch. However, I am starting to get a little jealous of Mark. When we first got the kids I was home in plenty of time to see them come home from school and we spent a lot of time together. I was their favorite :). But now I am feeling like it is starting to change. Since Mark has had his surgery he has not been able to work so he is home with the kids and gets to spend all of the time with them. He is the one helping them with their homework, feeding them and spending the time with them. I am feeling a little left out. Yesterday I had to work all day and I mean all day I was there for 12 hours. I came home to them playing in the yard and having a lot of fun and it made me sad. Is that crazy that it made me sad? I should be happy right? They are playing with their Dad what more could I ask for? Well, I didn't like not being able to be a part of that. It was really hard for me. I want to be able to spend the fun times with them. By the time I get home I have to fix dinner, finish cleaning the house and get them ready for bed. This isn't fair!!!!!
