Cheating
If someone cheats on me, it's done. 1 time and that is it. I couldn't trust a person any longer because how would I know if they wanted to do it again? I would become very cautious with everyone and would have to constantly ask where they were going, with who and what time they were going to be back. I always said that I would never be friends with that person again but that isn't true. I'm friends with MC but our friendship will always be much different than it was before. I can't fully trust her and probably never will for a long time. It would be the same with any other person who did that to me.
Now, if I were to cheat, I would never forgive myself because I hate cheaters. It would be a blow to my pride and put me on a lower level than everyone else. I would tell the person I'm with that I cheated and it is up to them to decide what to do with our relationship. I think the thing that would hurt me the most if I cheated would be that everyone would know. The person that I'm with would tell her friends that I cheated and I would forever be known as a cheater. I could never reestablish myself as a better person among those people and even if I did, they would still remember.
Why do people cheat?
I assume people cheat because they aren't sexually or emotionally satisfied, dislike the person they are with or want to have two or more partners. I guess you could also put in sexual fantasies because they want to have that experience with another person just one time. That would probably fall under sexual satisfaction though. Whatever.
Reasons not to Cheat
I would never cheat because of what I stated above about the friends knowing and the blow to my pride. Also, it would be financially difficult especially if that person you cheated with wanted a relationship (i.e. giving gifts for birthday, holidays, dates, etc.). Essentially, you would have to lead a double life with the first person if the second one already accepted that you cheated on another girl. She would probably also want you for herself and pressure you to leave the other girl which would cause arguments or the possibility of her telling the first girl what you were doing. If the second girl didn't know then you would have to lead a complete double life with the friends and family meeting her, the dates with the possiblity of being seen with that girl and the internet. The friends and family meeting her would obviously set off some alarms and for me, my grandparents and mother would not have it. They would probably tell the girl that I was cheating. Secondly, the possiblity of being seen is too great. There's too many people that know me or at least recognize me so that would definitely fail. Lastly, the internet. There's facebook, myspace, email, aim and too many other things to name that would get you trapped.
Overall, I don't know how people do it. I don't want to know how people do it. I could care less about these people because they cheat. I promised myself a long time ago that I would never cheat and I will keep that promise until the day I die.
