Unlike most of you, i'm not married..
Trust me, being in a relationship does not lessen the burden... the burden just changes to:
"When is he going to pop the question?"
"When will we buy a house?"
"When will we have kids"
Or how about "Oh ****! Am I pregnant? What'd we do?" (NOT my question about my own life... I've just seen it happen) then it becomes "Why am I the one responsible for all the childcare?"
"Why won't he take out the trash? Is he really *that* lazy?"
Oh and the ever persistent question you will see in this particular forum:
"Why does my career take second place to his?"

You just have to take it all with a grain of salt.
If there is one thing I have learned in life, it's that you can't really *expect* things to happen, ya'know? If you just go with the flow, life is much more bearable than comparing it to what you think life should be like now.
And that's applicable to all ages

BTW, I agree with Alison... making changes in your personal life helps loads. Simple things like keeping your apt clean, making good meals, working out and staying healthy, paying your bills on time, etc. all make you feel more grown up which definitely helps with the QLC IMO.
