Yes John F Kennedy did cheat on his wife. Marilyn Monroe was his most famous extra-marital date. There were a host of others. He kept a suite reserved in a Washington for the purpose of entertaining his female friends and his liaisons with some foreigners attracted the attention of the FBI for being possible spies.
No Lee Harvey Oswald didn't like JFK from the start, so he took the opportunity and killed him. Well, actually you are pretty close. It was Aristotle Onassis who had JFK killed so he could get to Jackie. Think about it. He was the richest man in the world at the time which gives him the ability and power to organise a hit on the President. He was a gun runner so he had access to weapons galore. He ended up with Jackie - motive. He could sit back and watch everyone else take the blame - the CIA, the Cubans, the Mafia, the Russians...
