I cheated on my boyfriend 3 times and I don't know why because I still love him what can I do?

Look for someone else and give time to yourself first. It's due to your innocent and emotional kind of behavior he is cheating you only. Be practical my dear. You are not loving some so as to get cheated by someone. Just understand that you're a nice soul and should be loved by someone who is an ideal for you only. In real sense he's your Mr. Right. Are you getting my point. Wait for the right person and he'll come to you and pick you up just like a precious flower in the beautiful garden. Wait till that moment.
