Love someone so much you can't breathe

I don't have many people in my life that I can vent to so I hope me coming on here doesn't offend. I've always been told writing everything out makes you feel so much better so I'm giving it a try. I'm young, early 20's and I do realize I have my entire life ahead of me, Lord willing. Over the past couple months I've been completely consumed with someone. Not in a way that seems to happen with everyone else but I feel as if I'm on the outside looking deep into a novel that I can't take my eyes off of. This has been the hardest challenge of my life, loving this man. It has not been easy. We both have fought so hard to get to where we are. Originally when we met we had no intentions of being so in love. We both had just got out of a serious, long term relationship and was just looking for comfort. He slowly over time became the very best friend I never had. We took steps to turn our friendship into something serious. As I stated before it was not easy. Of course considering the way we met there were many trust issues. There were many fights. Many slamming doors. Many nights being so mad with each other that all we could do was hold each other and cry. Those little moments, looking back now, have built us to a point of being so open and so honest. I look at him and feel as if my heart is going to rip out of my fucking chest. Sometimes I just sit there and cry because it's a feeling that overtakes my whole body. It's not something I've ever been through before. A simple touch from him ignites something inside of me that is so overwhelming. The way he looks at me, grabs me by my face and tells me he loves me, makes every fiber in my body go numb. I say that I'm venting but I guess I'm really not. I just want to share the fact that being in love is so incredible.. yet so fucking terrifying. I want to run because the idea of not being with this man for the rest of my life makes my entire body want to shut down. But I guess that's the whole point right? Finding your soul mate?
