It doesn't sound like she's got a great deal going for her. She's with a douche for a very short time, she got pregnant by accident, and now she's stuck either with a douchey husband or will have a messy divorce when the baby is born and she realizes what a massive douche he is. That makes me incredibly nervous for her. I do hope things work out, they just don't typically result in a fairytale ending.

I don't think you're angry at her so much as you're angry at the lack of progression in your own life. She didn't do anything wrong and you're smart enough to know that. You just want things to hurry up and go the way you want them to; you're feeling impatient. I don't think that's weird or anything. But you know, you're either with your fiance because any ole man will do or because you love him for the person he is. If any ole man would do, you could have chosen to get married ages ago to who-gives-a-crap-who. You chose this person for a reason and that's special. Same thing with having a kid. You could have had a kid ages ago if that's all that mattered to you, but I'm guessing there were other things you wanted to consider... You wanted to make sure you weren't living with your parents, or that you weren't flat broke, or that you finished school, or that you were married BEFORE the baby was conceived.

My point is that your life is a series of your choices. You didn't miss opportunities or anything; you chose to do things this way for your reasons and circumstances. You didn't just marry any ole person and get pregnant at any ole time. Those things by themselves aren't special; it's the context of those things that make it meaningful to you.
