It would depend on the lover and the reason they were exed.
Whats to 'believe in'? There can be countless reasons why or why not folks should be together, whether they have done it before or not. We can't know what is happening/has happened in a pair of lives that would bring them to such a decision, though we can hope that it isn't a fear response; 'better the devil you know than the one you don't' as it were. Wish them well, move on...
Strictly as lovers or in a relationship?
Possibly. Imagine you had a chance meeting with your boyfriend/girlfriend from when you were 18, 25 years or more since you last saw one another... you'd both have changed a lot since then, but maybe you both still have those characteristics that made you attracted to each other. Who knows - it might work out.
Only if they want to. Sometimes it might work. It will never work if either of them keeps on mentioning or asking about relationships they had while apart. To be together again they each might have to drop a few friends.
Ignorant people still want to ask me about my breakup with my ex. I start to cry and say everything was OK until she ran off with that circus clown. LOL
In general I would say, no, their ex-lovers for a reason.
Sure, after a little while apart you forget the things that drove you apart -- until they all appear again,, Not generally a good idea, in my opinion.
I suppose it could work, never has for me.
Why not? Some of the most lasting marriages that I’ve seen are the same ones that repeatedly broke up and reformed. Of course, there’s the added value of drama.
Why not ? As long as they got along.
Not every situation is the same.
Do people really change? Somehow I doubt it, we evolve but our core personality is there by the time we reach early adulthood most of what we are is fixed. So whatever didn't work before still won't work if we give it a second chance. Sometimes we just want the familiar even though we know it isn't good for us.
I have done it. All the old issues are still there. If it crashed and burned once, it will do the sam
e--only worse! the next time.
