Nice thread!
I'll go straight to a general view of how i see some 'couples' dealing with their differences.
If a person you haven't met but have been chatting with, expresses their affection ( no, not undying love) for another, i see that as normal, why would i talk to someone for weeks, continuously and not feel a thing?
I feel connected to someone on the site, he feels the same way and we are taking things slow, but we hardly think each other to be mad. This is probably why we get along so well. We are both two human beings, in search of love. We don't betray each other's confidence, or resort to psycho-analyzing each other or using anything we say about how we feel for each other, as weapons. While the overly-pessimistic judge, we continue to grow together.
It's all natural reaction and there is no specific time frame for where this ends.
As for those who declare their undying love shortly after talking, they are probably confusing the connection they've made with someone for 'true love' or they could actually be feeling it. It doesn't make them bad people, just different!
Then, there are the scammers, we can all tell their intentions, 5 minutes into a conversation.
Why do most people think they know the proper way the other person should love them? I say, go with the flow.
I can't stand needy men, i also can't stand manipulative men who want to control the way i should feel, because they somehow feel clever. I will leave them hanging for a better man, in a split second and not feel a thing. Life's tooooo short to lose yourself, trying to boost other people's esteem.
If love is so unbelievable and false, then i have no business trying to build anything with a person. It's such a turn off to be pessimistic about something so wonderful. I hope never to meet such men.
For those who insist, even when i am clear about not wanting anything to do with them, i either ignore them, remind them it's hopeless or pray for them.
That was long.
