Not to be judgemental... but its damn easy to have opinions on people in situations that you aren't in. A year ain't much to give up for a great husband and beautiful child. Getting knocked up because u had unprotected sex w/ some guy means u basically forfeit a lot of your choices about ambition etc. for responsibility.
One of my best friends from HS and our class valedictorian basically did what u are talking about. She finished an electrical engineering degree, graduated summa cum laude, had the entire degree paid for by scholarship & married a guy who got deployed in the navy sub program about 6 months out of college. She's got 3 beautiful, smart as hell kids and hasn't worked. She has moved her family about 10 times, including to Italy & back 2x while moving with her husband's assignments. Now she has 3 kids who are multi-lingual and she has been successfully writing childrens books for about 10 yrs.
I've got degrees up the yingyang, a successful job and I'm in my mid (to late) 30s, living w/ a cat and fucking hating life alone. So... yea I had all the opportunity in the world to follow my amibitions - I've accomplished every one of them that I set out to do. But I'm not real happy with the current outcome.
I guess its all relative, but its certainly not worth an argument that involves him wanting to smack you. Shit, keep it in perspective already.
