First of all stop making this about him! It doesn't matter what HE wants! You are about to become someone's mother. Your focus now ought to be on getting a education or some type of training which will lead to a career path that will allow you to support yourself and your child.
Don't allow yourself to be manipulated. When a guy says he's "confused" he's basically looking to keep you as a "booty call."
The last thing on most boy's minds is becoming like their parents! They aren't mature or ready to get an apartment/mortage, provide financial support for baby food, clothes, health insurance. They want to party with their friends, play the field, and enjoy their "freedom". Getting married right out of high school is considered a nightmare for most high school boys. It's like watching their life flash before them. Boys don't grow up playing with baby dolls, pushing strollers, cooking with Easy-bake ovens. They have not been dreaming of getting married. It's unrealistic to expect a teenage boy or a guy in his early 20s to be ready to for a commitment of "until do us part". Most men don't start thinking in those terms until they are in their late 20s or early 30s.
Your time for worrying about "boys" is over with. It's time to start approaching your life like an adult. Learn from your mistake. (I'm assuming your pregnancy was not on purpose). Make sure if it ever happens again it is within the confines of a loving marriage with a financially stable (man) who is NOT confused.
Teens need to quit pretending that their high school relationships are on par with "adult relationships" or "marriages". Being a teen means learing about one's self, exploring life, and trying to figure out what you want to do. Most people don't end up "happily ever after" with their high school or college sweethearts. You might also want to read books on how to select the right type of man for yourself and child in the future. You might check out my book on Amazon. "My Cat Won't Bark! (A Relationship Epiphany).
"Never separate your mind from your heart when making relationship decisions." Best of luck!
