Gosh, it's hard to think of specific examples.
It's the little things, ya know...it can be something that he says, or something that he does, or even just a look that says what he is thinking...Like if he does the dishes and cleans the house when you are really tired and on your way home, and you are dreading the housework. And then you get home and it's already done. That's the BEST!!
I personally like for my man to make me feel safe and protected by him...that doesn't cost anything either. I know, it all sounds very romantic...

...but it is!
