Real? Yes. Tangible? No. Why are you trying to touch feelings anyways?
In any case, love isn't easy. Love isn't pretty. You'll still get in fights. It'll fade if it's not cared for. It'll fall apart if there's any problem that occurs that you won't talk about, or if you believe some actions are irredeemable.
In the end, love is about all the hard days you come home and find comfort in your lover's arms. It's about working out your problems before you go to sleep, even if it takes all night. It's about listening, and knowing when a flower, or a nice romp is called for (generally the latter is when you want one
). It's about being able to talk about things. Anything. Everything. Especially the things you don't normally talk about with other people. Even the things you don't normally think about, and trust me, that's the hardest part. It's about opening yourself up to be hurt like you've never done for anyone else, and having someone else open up like that to you. It's about knowing when your lover is honestly and truly sorry, or when they've given up on you.
In a way, I think it was easier to create lasting marriages when arranged marriages were the norm, because nobody thought "Hey, I'm really attracted to this person, I really like hanging around them, it's always going to be this way." They thought "Hey, if I don't marry this person, our families will suffer, and if I don't stick it out, our children will suffer, so I'd better try really hard to make this as pleasant as possible for the two of us, and maybe we'll grow to really care for each other in the end."
Love is high-stakes, long-term emotional gambling, but you can stack the deck in your favor.
