He's showing his true colors. When in a new relationship people tend to try to seem their best. They try to not seem as gross. They try to seem more polite. They try to dress better. Once they become comfortable they slack off. The probllem with that is, their partner only know the part of them theyve been showing and doesnt know that whats been put up is an act. Dont believe me? Just look at first dates. how many of these people trully act the wya they come off to be. Well same with living together, he's now slacking off and acting like his real self. He may not put as much importance into the relaiotnhisp and may have goteen comfortable where he is. Basiclaly, he's taking the relaitnship for granted. What you need to keep in mind is that, this is him. This is who you could be marrying. It seems like you two are out from the honeymoon phase and if you can deal with this forever, it may be best to slow down the relatioinship and think about where you want this to go. First step, talk to him. Try to help him improve. Tell him that you arent judging him or being controlling (atleast you arent trying to be) but that it puts stress on you when he doesnt help out. If he doesnt change you may want to politely end this relationship.

Time for an ultimatum......serious talk about how this is making you feel (I feel......when you.....I need you to.....You fill in the blanks). He is being disrespectful to you and nit won't get better unless he believes you will leave. This is NOT a healthy relationship if he doesn't revert to his 'other' behaviour. It is a test. If he fails the test...flunk him.
