Dating vs serious relationship
If you are going out with someone on a regular basis, and you and your partner have agreed to date only one another, then you are in a committed relationship.However, if you are dating a person and neither of you have agreed to date exclusively, then you are not in a relationship and you are both free to also date other people.
Relationships are developed through constant communication and being with a particular individual.
Prior to talking, you should sort out how you feel about the relationship, aside from anything your partner may feel, and decide what you want or need from your partner.
The book, "Getting Love Right: Learning the Choices of Healthy Intimacy," suggests asking yourself the following questions: "Are the people you are presently involved with capable of giving you what you want in a relationship?
As such, the activities centering on the process of dating would involve doing fun things together such as going to the movies or the beach with the central theme always trying to get to know the other person more.
For this reason, a man or a woman can date more than one person at a time.
