Is it wrong to want to get out of the house, and I mean move out? I really feel better when she's not home, is that sad to say?

I've been GAL, but honestly these last few weeks, I feel better when i'm not around her. I'm not sure if its my weakness with patience, not see results fast enough. Or, honestly im just tired of dealing with her negativity.

I was in a GREAT mood yesterday, we went to lunch, and by the end of lunch she dragged me all the way down that it wrecked the rest of my day on into my evening. I was upbeat, serious PMA, and she is just so depressed its a bummer to be around. I went to my dance class, and went and hung out at a friends house till around 8pm, felt better, then I came home and bam, I wanted out of the house again. This has got to be some kind of phase, I mean I want the marriage to work. I cant even recommend her seeing a dr. without her saying she's fine, then getting bitter, so I stopped that, no more ideas from me. I cant fix her, I know that, but its rough watching her waste away, or maybe its just reflection on her part, lol.
