same line, different tune.

what more does one want out of a relationship when it's healthy, peaceful, comfortable, fun, stimulating, what gives it the za za zum? the butterflies? if it's not there, what do you do? how many more times can i hear "you're everything i need, but". what brings the but? i have been told i'm beautiful, wonderful, a great model of a mother for future kids, intelligent, etc. and then comes the three letter word in the english language i despise the most; but. but what? am i just adequate on all accounts?
