Ex problems

Okay, last year I dated a guy named Charles. He was nice guy. Then we broked up after a few months of dating. So this week was HSAs and today was the Biology HSA and Charles sat behind me. The whole 3 hours of testing (plus a few breaks) he'd been poking me. As soon as the testing was over and the bell ranged, he'd put his arm around me and walked me to my Homeroom and the remaining two class periods. He took my arm and put it around his wraist.

Question: should we get back together?
