If a man or woman behaves in an inappropriate way, can the other half change it?

One can give it a try, but it's my belief you can try your best to change someone but they will only change only if they want to change
_{Here's an example i have a family member who was way too important for me, it's not that (that person) was in alcohol or stuff the thing that always bothered the whole family was (that persons) behavior way of doing things, the whole family always gave () time, that one day (they) will change, we constantly always told (that person) to stop going a particular act because that was not good, but () never changed, it's not that () don't love us, but didn't changed because (that person) the one we call our family was happy with what () was.}

And is it worth changing another person at all?

I truly don't feel it's worth it, yes give it a try but don't jus keep on hurting yourself just to bring someone back to life, tell them they are wrong help them heal, but what's the purpose of all this when all will be in vein and you know it. Not everyone deserves your attention and care.
