My husband thinks we are all going to die in 2014 because of Planet X

First of all, 2014 is in three years, not four. Planet X, depending on what you think it is, has either already been discovered ( a dwarf planet officially named Eris, informally named Xena before the International Astronomical Union granted it the name Eris), or it is a fictional planet being used hoaxers to scare scientifically illiterate and gullible people like your husband into giving them money for survival kits. Your husband needs professional psychological counseling. Does he have postpartum depression? Some husbands REALLY DO go through this. They project their wife's emotional state onto themselves. If you have postpartum depression, and your husband is contributing to it ( you are psychologically codependent on each other), you may BOTH need co-counseling together. If you can admit that you are depressed and try to make an appointment with a s psychologist or psychiatrist, you've won half the battle already. Good luck to you and your husband.. I've watched how a co-dependency, a denied alcohol problem, and a mistress her ex refuses to stop seeing, have ripped a good friend's 30 year marriage apart. The sad thing is, even though she divorced him, they really still love each other. Her depression and dependency on him to bring her food and groceries and his dependency on alcohol just can't be broken by either one of them alone.

So, your husband is the astronomer royal at Grenwich and knows everything there is to know about astronomy?

He must have remarkable knowledge indeed, as every professional astronomer on the planet will tell you that the doomsday thing (whichever out of the hundreds doing the rounds at the moment) is a pile of steaming crap.

Just try and humour your husband for awhile. He clearly watches too much tv, and is easily led by whatever fad is flavour of the month. Just wait a little while and he will grow out of it. Trust me. In a short while he will have grown out of the doomsday thing (unfortunately he'll probably move onto the next fad, whatever it turns out to be).
