Someone said :
Could you give examples (personal experience is fine

) of the difference betwen the two. Because I feel that is swaying towards 'open connections' which are definately casual.
Let's take John as an example, as I would not give a personal example, for obvious reasons.
John is going out with Peter, a boring lawyer, Mark, a hot brick-layer, and Steve, an average looking student.
For the past 6 months, John has been going out with them 3, sharing week-ends and holidays. Even sharing a night 2 days a week.
John is not sure that he even loves any of the 3 but he reckons that Peter might be a good party, Mark a hot date, and Steve might develop an emotional connection as they are similar. He likes them, but no spark exists at the start.
John wants to settle, either with the best match, or the best party, He is not romantic, he knows what matters in a relationship but could never find it in the same person.
Once he has chosen, he will either stay with only one of them, or none of them.
He never lied to them, but they do not necessarily know about the other 2. Only mark knows.
He never committed, or made serious plans. The others know that they are not technically exclusive, but they would introduce him as their boy friend when socializing, and he may have met the parents of Peter and Steve.
He will only introduce them to his parents if and when he has chosen.
