My ex and I broke up months ago and I can't get over it. He broke up with me because I didn't show a lot of affection that he wanted (I tried so hard showing how much I loved him, but it was hard because I'm shy), and I had many things to do that made me push him aside a little bit. At first, I didn't react much. But over time, I felt so much regret and frustration with myself. I'm sorry.
