Whether it's something as small as the last piece of chocolate or the window seat on a flight, or something bigger, such as a spare concert ticket for a band you love, your man will always be ready to go without in order to make you happy. It's one of the best ways to tell if he is in love with you or not. Of course, you shouldn't always be taking him up on the offer, but it's nice to know he's willing to sacrifice his own enjoyment for the sake of yours.
When it's freezing outside and he gives up his jacket, take note of how much he's willing to give up for your basic comfort and take a moment to appreciate it. You've landed yourself a keeper if you've met someone who will be happy to go without every time.
