I'm not sure. Sometimes you have to accept that love will usually have a condition to it. Unconditional love is quite rare and probably not even possible. We are usually getting something when we show love and give love. Sometimes you get something physical in return. Other times you're getting something non-physical. You're usually getting something when it comes to love though. Usually dopamine. The never-ending mission to get dopamine. Though people do like to throw the term around. Others also like to try and apply deeper meaning to "love" or they try to make it sound deep when in reality it isn't really all that deep at all.
A confusing idea- I love my dog but I can also love a girl. Same word, different meanings. I'm not able to have sex with my dog and I can't have long emotional talks with my dog where we can show understanding of one another. (Though I probably could actually-) Though I still love my dog. When it comes to a girl the only difference is that we can have sex and do normal romantic stuff. Along with a possible understanding of one another because we as humans love to be understood and recognized. It's not as much as loving a person but more finding someone that you're able to connect with and feel free with that doesn't judge you. The dog doesn't judge you if you want to talk about anything. Hopefully the other person you want to share love with doesn't either.
I am sort of just throwing goop at a wall and seeing if anything sticks.
*cough*
Though that is not how every relationship works out. Sometimes it is solely physical and a way to secure dopamine. For sex only. People will still say it's love though. They love the other person because they give them sex. Well more like they just love sex. They love money. They love power. etc etc etc. For some that is okay, for me it would seem a bit tiring and a shallow existence. I wouldn't really want to deal with someone who doesn't understand and accept me for me. I think I'll stick with the dog and my hand.
In the case of the dog. The dog loves you because you feed it. We use the dog to get another form of love. Soft furry and cuddly love that will listen to anything you say without judging you. Mainly because they don't understand most words. A lot of times people just want to talk to a wall with a pulse. We can still get limited physical love from a dog or a cat. Any animal really. Just being able to hug something is nice.
Another thought, friendships. What about those. Is it possible to share deep feelings with your friends. When does it cross from a like to a love. A bromance. I guess that is up to you to decide. Some people can actually love their friends. A lot of people like their friends. How many love their friends though?

I guess my thought is that love is the ability to share deep feelings with another being. The feelings you normally wouldn't share with just anyone.
