For me it is getting that butterflies in the stomach feeling whenever you are around them/talking to them/thinking about them. That is my serious answer.
Non-serious: He doesn't abandon you at a restaurant after drinks and dinner and leave you with paying the whole tab.
I know I'm in love when all my thoughts of the future include the person I've fallen in love with.
i don't know exactly how i knew.. but i remember initially feeling very overwhelmed that i loved him. like it was some big weight following me around. and until i got the nerve to say it (which was ridiculous, he had told me he loved me months before) nothing felt right.
& what i'm curious about is when i get to stop loving him.. will it just fade away? will i notice? blah.

I think you'll wake up one day with that same weight lifted and everything will start to feel right again.
I knew I was in love when I saw my husband's bad side and yet I still saw myself growing old with him.
I knew I was in love when my husband showed love and affection toward my disabled mother.
I knew I was in love when a deaf elderly woman fell outside our apartment building and he ran to her to help her, face shrouded in fear and compassion.
I knew I was in love when I saw how much he loved me.
I don't think I've ever really been in love before. I hear it's pretty nice though.

I can tell that person anything without the fear of judgement and I can see a secure future with this person.
When I can be totally myself and he still loves me
When I spend my damn money.
Non-serious: SPARKLES. And a musical montage.
Serious: I knew that no matter what, I was in this. It wasn't butterflies in the stomach (I didn't get them with my DH. In fact, I knew I was going to marry him before I even 'felt' in love with him. He was a great guy, still is, and I knew that he was worth investing my heart and soul into). It was just... I knew I was in it for the long haul, come hell or high water. We got married soon after :)
Srs: As cheesy as it sounds, the first time I saw my SO in person it was like a little voice inside me saying, "Oh - there you are. I've been waiting for you." and I knew he was going to be someone very important to me. His face is the one I want to see before I go to sleep and first thing in the morning. When something good, bad, silly, or totally mundane happens, he's the first person I want to tell.
Nonsrs: I don't bug him when he's watching football. That's love.
Once the initial infatuation period is over and you see all sides of a person and still love them.
People told me for years, "You'll just know." They were right.
