What do you do if your new girlfriend is living with her ex-boyfriend because she can't afford to move out?
You should tell her how uncomfortable it makes you feel. See if maybe she can get a cheap apartment with some friends. Also, go hang out over there for awhile maybe you will see they don't have any feeling for each other and it will make you feel better.
Because wealthy children could afford to go to college; thus receiving a "draft deferment." Most draft aged men had to work for a living, and couldn't afford to go to college, as that required carrying 18 college units to avoid the draft. 18 units was full time school. So the men that couldn't afford college had to go to war instead.
