What can you do to maintain pleasant relationship despite changes in moods?

you ask ur partner if they can make some changes and you can make changes too....just remember to use communication

Yes they do so say that the color was red then you might think danger.

By communicating often everday. This will make you and your partner become closer and will be able to trust one another in what they do when your not there.

I wouldn't count on it. People are the way they are for a reason. Don't stay with someone counting on them to change. It probably won't happen. Plus, then you will be unhappy when they don't change....
