<human>: Can you provide a brief overview of the text?

I started counting calories in January and I lost 15lbs in three months. Awesome. My girlfriend and I joined a gym two months ago. We both go a minimum of three times a week. I use a routine the gym provides on their website. One day of full body weight lifting and one day core/cardio. Since I've joined I've seen zero weight change. I ate 1800 calories a day the first month which I realized was too low. I started updating my calories and ate 2200 for the second month. Zero change. I would have thought I would have shed **some** amount at least.

I've lost weight before going from 290 to 177 at my lowest two years ago. I got content in my relationship and also started dealing with some chronic pain. Over two years I got back to 237. I know the scale lies and muscle weighs more than fat. I've read about glycogen stores and retaining weight when exercising. I've searched out every piece of information I can but I can't seem shake the thought that I'm doing something wrong and wasting my time. 

So, what do I do now? Has anyone had a similar situation? Do I keep at 2200? Do I drop down? Is this par for the course when you exercise? Do I stop lifting weights? Do I up the cardio? 

Part of me knows not to expect miracles and this is a long term change. I could use a little outside input to help squash that annoying little fat voice in my head. Thank you in advance for any advice.
