It sure will. Your poor kids will be in emotional turmoil and need counseling and probably even anti-depressants. That's what happened to my son. He was a normal happy kid until the divorce. It tore him apart. We had to attend weekly counseling. He recently admitted to me that he cut himself because he hated himself so much. He also would sit in his room and stare in the mirror hours on end while I was at work. He even contemplated suicide. His faith in god kept him from it. That's another thing people don't consider when they think of divorce. Your kids are gonna have tons of "alone time." What are they going to do with it?
AND this....EVERYTHING will be on you. I'm talking household duties. YOU will be doing all the work. I mean ALL of it. You won't have that helping hand around anymore. Inside, outside...it's all yours.
You also will have to provide ALL the transportion for these kids and their extra-curricular activities. I'm telling you, it's a lot.
AND you'll only see 1/3 of his income. Can you live that way? DON'T CONSIDER DIVORCE over such seemingly small difficulties.
Now think about this step-kid. You are investing in his/her future. Do you want this kid to have wings or not? Do you want him/her returning to your doorstep? You don't need a boomerang.
I don't mean to come down hard, but I'm living this right now. I'd kill to have a little helping hand around here. Please reconsider.
