We all want a person for life. We may spend our whole lives looking for that one person. But the truth is, we can't look for them. As long as we keep looking, it will keep eluding us. We will get frustrated, we will get impatient, but we have to let life figure it out for us. We think we know ourselves the best and who would fit best with us. Sadly, we don't know ourselves as well as we think. Truth is, we have to let life figure out things for us because it will find the best person possible for us.
Once you think you've found the right person, you have to decide for yourself from then if you can see the rest of your life with that person. We all can put on fronts when we first meet someone and act as someone other than ourself, but who someone truly is is who you should fall in love with. Not just them when they're wearing their makeup or acting proper around your parents. If you can't be in love with how someone is on the inside and outside, then they aren't the one for you.
Fall in love with the person you can be endlessly silly with, but then be completely serious right after. Love the person you can call dude and babe in the same sentence. Adore the pictures they send you when they aren't even trying to look decent. Those are the pictures you should appreciate most because they show who the person truly is, underneath anything they try and front themselves with. Take pictures of them when you think they look beautiful, even if they hate them, they will appreciate the fact that you love them.
Go after the love that is imperfect. It will be your perfectly imperfect love that you two share. Nothing is easy when it comes to this stuff, but there is someone out there who can make it a little easier to handle. Through every stupid argument and disagreement you two have, love them endlessly because life picked them out specifically for you. If you have someone who loves you unconditionally, don't let them go, ever. And most importantly of all, do the same back by loving them unconditionally too. Appreciate what you have because not everyone finds that person for them.
