4. He loves to make you happy

A man in love makes you feel loved. He won't compare you with his ex. He won't openly flirt with other women to make you jealous. He's great to be around and he loves to make you smile. Men in love don't have excuses for why they can't find ways -- they don't need to be nagged to do this or bribed to do that. "If you're with a man who puts up a fight when it comes to doing something that will bring a smile to your face, he's probably with you only for sex," explains McKeithan.

5. He loves spending time with you

You can easily spot a man in love through his attitude. "If he loves you, he wants to spend time with you, and everything you do together is a pleasure, not a chore," says McKeithan. You can be watching DVD re-runs for the tenth time on weekends, running errands together, or some other less-than-fun activities, but he still enjoys your company.

6. He is not easily annoyed by you

"Even when you break his favorite mug he is more concerned with your well being than a few shards of porcelain," reveals McKeithan. That's not to say that he's a pushover, but he is certainly not a man who is easily annoyed, angered, or agitated by the things/mistakes/accidents you do.
