Just having a relationship is not enough. Relationships can be good, bad, toxic, and so on.
You always have to work on them and make efforts every day. Take time in your relationship and know that it is important for a person to receive warmth, love and care. Forget about selfishness and sometimes you even have to sacrifice your own interests for the sake of your loved one.
When one person is caring, the other person will try to match it and be caring towards you. The more you compromise, the happier your relationship will be.
