Break Up

My boyfriend of a year and four months and I broke up the other day. I made a huge mistake. I made out with another guy, which is what triggered the break up, but now I just feel so stupid. I keep sending my… ex text messages that say, “I love you,” but he doesn’t reply. He said he’d always love me, and I just can’t get him off my mind. Everything reminds me of him and I’ve slept in his shirt every night since the break up.
