Love?

I fell in love with a sarcastic asshole. Someone that stopped me dead in my tracks with sarcastic clap back after clap back. Always givin right back anything I gave them. They loved me in the "I'm gonna gas on you all the time" kind of way. Which is exactly who I am too. Two years later some how they have turned into an overly sensitive pushover that cries all the time. Come to find out that's who they really are. The person I fell in love with was an act. They stayed in character just long enough to get engaged. Now I'm supposed to be marrying someone I can't even be myself around because suddenly my sarcastic quips aren't appreciated. Sometimes I wonder if I'm making a mistake. Then I'll think about some of the other bits about them that I do love. That maybe I just need to throw away the sarcastic part of my personality. They care for me so deeply. I've never felt so honestly loved. I've never cared for someone and wanted to grow with someone this way before. I love them , I really do, but if I've been given thia much pause that's a sign to get out, right?
