I'm pretty sure that when you initially started dating your partner the two of you did not sit down...
1. He Loves How You Look On Your Worst Days – Remember how much effort we put into looking our best during those early dates? Of course. All of us want to look and feel good when meeting up with a potential partner. Then there’s the actual relationship. As we spend more time with each other, comfort levels build, and our need to impress declines sharply. We’re free to wander around in our pajamas, stain our shirts, and forgo the hair gel.
2. He Isn’t Afraid To Make Sacrifice – When we are in love, it’s very much easy to make personal sacrifices. And when a man is with his true love, he will feel discomfort to see his woman unhappy. He will desire to sort out the problem and do whatever he can. As such, making sacrifices for your happiness is one way a man demonstrates his love for you. He will almost always put you first, even if it means changing his plans or stepping out of his comfort zone.
3. He Shows Vulnerability – Men being men, we’re cautious about showing any behavior that can be perceived by others as a weakness. In love, however, this deeply ingrained attitude often falls by the wayside – and we don’t care. If we’re in love, we’re far more comfortable with feeling and acting vulnerable. Vulnerability will assuredly make several appearances throughout a relationship – especially if we’re with you only.
