What are the signs that a man is in love with a woman?

Although, I'm no expert, most guys tend to be somewhat as obvious as girls. Speaking as a girls point of view, it could be just mere glances and smiles your direction. Eye contact is a good sign. Also, when a guy sounds stupid or says something stupid, that's usually a good sign. It either means he doesn't know what to say in front of you or he's afraid of sounding stupid. In extent, he will also find excuses to touch you. The old saying about a guy being a jerk and then liking you is not true. If he likes you he will try to impress you, not scare you off. If you want a guy to like you, make sure you're "inviting" because he doesn't want to be unwanted.
