I am wondering. Can a person actually change? When I was 17, I “cheated” on someone I was dating. He wasn’t my real boyfriend, but we were spending a lot of time together, and we both had feelings for each other. Anyways. I have since then never cheated on anyone else. I realized how badly it made the person feel when I came clean. I am wondering, if my ex can change (he says he is working on himself to be a better person) or any other cheaters in general?
