Emma, sorry for the guy situation.... they think so backwards that they nearly think forwards (nearly...)
Sounds like you're determined with the healthy eating and exercising tho, which is great, cos i know how hard it is sometimes when u feel a bit urgggg with stuff just to grab that huge bar of choc (my bad, i have to say!)
i've not had quite the situation you've had, but similar. i sent the guy a text telling him how i felt, he ignored it, and i then proceeded i never sent it! things were weird for a while, and i still feel a bit weird sometimes as he has a girlfriend yet i spend more time with him than she does, go to his family parties, and have met his entire family. i stay with him chatting til 3am, yet we're just 'friends' still....this thing must be so hard on you, im sorry you're going through it!
hope things improve or level out with this for you soon. like classes and weightloss aren't hard enough, then they invented BOYS!
