no, not tired of it. it can be difficult sometimes, if you start to feel crowded. don't dwell on the negative PB, if you do, you'll FEEL negative. a lot of your feelings are based on how you perceive things--if your perception of your wife is that she's a drag, she WILL BE a drag. be patient, it will pass. meantime, don't tell her you're sick of her--that won't help.

hang in there, it'll get better! also, let her know that sometimes you just need downtime, let her know that you need to stay home and relax once in a while. don't just keep your yap shut and suffer in silence, and allow resentment to build. heck, tell her you're not feeling well at the very least, and not up to it.
good luck!
