No poem or story exerpt this time...Just me and no BS

As I look around I see couples, lovers, fwb, husbands and wives...It s so nice when  I see them all lovey dovey and even when they fight because I know they will get back together and make up...
What I donot get is why people cheat on their significant other...Do they think it would be better with the other person? No, it will not be any better with the other person because they will want you for a little while...When the thrill is alive. When it ends, it ENDS...Did your vows mean anything to you when you said I do? I believe it did at the time...You may tell me the love is gone, the spark fused out...What am I suppose to do? My answer is TRY to make it work instead of talking to other people behind your spouse's back or just get a divorce...If you cheat on him and her then we all know your vows meant nothing
