What makes you think that if someone has so much power and control over you that they can make you feel euphoric, they can't use that power to make you feel so unbelievably hopeless and distraught? If you want to fall in love, you have to accept that your feelings are going to reach every extreme. from happy to gut wrenching. People will ask you why you're still with this guy when he makes you feel like shit, and the only answer you have is that he's the only person that can make you insanely happy and that without him, you don't feel a reason to carry on with your life. When you know that there's someone out there who can make your life so much better, you can't just carry on living your life normally - without them. Once you've felt love, you can't go on without it. That's the reason why we all put up with this shit because even though he's the reason for your heartbreak, he's the only one who can fix it.
