when you're in love
Ok - love is more than the fluttering of your heart and the butterlies in the stomach.
BUT IT IS ALSO THE FLUTTERING OF YOUR HEART AND THE BUTTERFLIES IN THE STOMACH
If that stays with you, when the challenges of relationships come your way, it makes those challenges much easier to walk through. The romantic squidgey bits of relationships are the jam in the sandwich - they help keep you together and help you remember why you choose everyday to share your life with that person. Dont get me wrong - staying because you promised to is the right thing to do but staying because you are in love is the better.
challenges come and go - but love remains and outlasts all else.
