Jademage,
Wow. That hits close to home. My wife and I almost split up for very similar reasons. This happened earlier this year. She never got a chance to go to college and was upset that I did. She started staying out late at night to have what she called "a college experience". Turns out this college experience was spending all night partying and avoiding any responsibility. She said that I was smothering her by being bothered that she would stay out to 3 and 4 in morning without even a call to let me know where she was. I was supposed to let her do whatever she what wanted without any questions. Needless to say, this didn't make for a very healthy, or happy relationship.
The advice I can give is this. Step back and seriously look at all the good and bad things about your relationship. If there is anything worth working for, do it!
My wife and I decided that we were worth working for. We went out and got some outside help, via a marriage counselor, to help us communicate better and become a stronger couple. Now, almost a year later, we are happier than ever! We both feel like we have more freedom and are "smothering" each other less.
I sincerely hope that everything works out well for you, your wife, and your son.
