Is it normal to love him this much even tho I cheated?

Your just a whore, it's normal. You were probably drinking and had a guy pay attention to you and you spread your legs for him. Very common. You have low self esteem. But don't worry, everyone wants to sleep with other people, if you don't want to your not normal, it's natural human behavior to have urges. The difference between people who cheat and don't cheat are the non cheaters aren't mentally weak. Cheaters can't stop themselves. It doesn't mean you don't love your bf or gf. For people that are to weak to say no to a random peace of ass when your with someone else, just don't put yourself in situations where you'll cheat. It's like putting an alcoholic in a locked room full of booze he's gonna drink, all addictions are stemmed from mental weakness, and it grows to a disease. Be strong and say no to random penis.
