If two people love each other is that enough to hold you together and do you think people can happily come back together after long periods of space and being apart with other people.

Good question, I don't know the answer to this one. I know that people do get back together after a long time of being apart. I can't imagine it though, as people change, and you might have moved on by then. I suppose people could fall in love again if they were given the chance.

Don't discount the power of shared interests and experiences. If you have none you have to rebuild from scratch.

Sure they can as long as its mutual. It just doesn't happen that often.

Every situation is different. I don't think that love and love alone is enough to hold two people together. It also takes commitment. I do think in certain cases that people can come back together after being apart for a long time. Again, every situation is different but it's a possibility.
