I still love him?

All day, everyday I constantly think about my ex-boyfriend. I day dream about him, I even dream about him while I sleep. We're perfect for each other, he still says we are today. We still sometimes talk through text messages, but we both not dare call. My ex and I have been apart for two long years, But when I see him in random places I start to shake like I'm about to have a seizure or something. We wont speak to each other if there is someone else with us. But if we're alone we will talk for hours. Is it normal to be married and be in love with someone you rarely speak to, your "forbidden" to see, and havent stop thinking about scince they day you met them?????
