Reading old Facebook messages

Back in December of last year when I was talking to JB he was already trying to get back together 3 days after we broke up. He was saying anything if not everything to try and win my heart over and get me back. He still said "ur mine" even when we weren't dating. He tried for months to get me back but I was just so stupid and a complete idiot to not notice how hard he was trying to get me back. I should have to my chances back then and no have cared about what anybody said like he said "it's what you want not what they want". I should have done what my heart wanted from day one but I didn't. And now look I'm laying in bed crying about everything involving him wishing I could call him mine. That will never happen again because I texted him and told him "to make you happy I am over you ok." It was a lie. I could never be over him because I've come so far and have developed such strong  deep feelings for him that won't go away. I should move on and let go but I just can't. I love him.
