Keeping on talking and making sure you are listening - and being listened to.
Compromise and appreciating the compromises your other half makes.
Forgiving them their shortcomings...
Being enthusiastic about some things that don't immediately interest you.
Sharing - I find this one tough, especially with the children.
Accepting that just because something isn't done 'your way' doesn't mean that it hasn't been done to a good standard.
Bothering to try and keep the relationship going and putting the effort in, even when you really don't feel like it because you know this is only a blip and things were great once.
Giving each other the support you need ie. catering for their needs, not just doing the things for them that you would like done for you.
Recognising that each person has individual needs and trying to help the other person in the relationship meet those needs ie I like family time for relaxing, DH likes alone time for relaxing - trying to make family time for me and alone time for him, so that we both get what we want and need.
Trying to be polite even when your other half is unblievably annoying...treat them with the respect you would a stranger.
Expecting high standards from them in the relationship too.
Remembering the great times that got you together in the first place, so you can try and weather the bad times.
Understanding that relationships change over time ad that this doesn't mean the relationship is over - it's just onto a new phase...and can be quite exciting.
