I'm not married or divorced, so I can't share that experience with you, but I just want to say that I believe love means caring and respecting your significant other. It doesn't mean a person doesn't make mistakes sometimes, but it does mean s/he makes an effort to think of the other person much, even most, of the time.

A person might think s/he loves another, when it's really dependency or attachment. S/he might care about the other person, but not enough that the other person is equally as important as him/her. I believe loving another means loving them equally as yourself, or even more. I think you need to love yourself a lot, too, so loving someone but sacrificing yourself completely isn't good.
