Totally agree with Perna. If she won't agree or makes more excuses, then it's been 'too long'.

Btw...how is it she hasn't noticed the lack of kissing or telling her you love her in over a month???! I'm assuming you're still being intimate, but no kissing? Something smells in the proverbial denmark and I'm willing to bet it's not just a moldy trailer and trashy roommate.

I do think you can find a place to rent on your own, even if it means another (cleaner, not nasty) roommate...maybe check the newspaper or go online to look...Being in the situation your in with that place and your gf isn't just physically unhealthy. It appears to be affecting your emotional health as well.

Take care
