When I divorced my husband years ago we remained very good friends until the day he died. We just couldn't be married but we were great friends. Sure we had our moments here and there of arguments but ultimately we were there for each other when it really came down to it.
i would agree on the being civil to each other, however i know some couples that are better friends now then they were when dating. i also know some couples that gett along better living together, but everybody has their ways.
i know 1993 sle would mostly agree w/ me sometimes life just sucks w/ each other but u make it work, (amazing how physical affection can make or break a relationship lol )
