hold it together matt.

either of two things have prob happened... its either an impulse flash in the pan thing... in which case you'll sort it with time.. or its been building for a while and she's taken alot of time considering what to do etc... in which case not alot you can do if it wasnt out in the open.

keep your chin up and put your mind heavy into finding something else you enjoy doing.

I feel really sorry for you, hope it all turns out so that you become happy in the end.
