Commitment in a relationship implies your intent towards your partner. Being committed means you’ll be there for the long haul through all troubles and are serious. Further, it's also important to make sure you both expect the same thing from the relationship. If you don't communicate your feelings regarding commitment and what you will commit to, you may get heartbroken or break others' hearts. So commitment is important for partners to feel secure in a relationship. It also allows partners to decide the best for their and their loved ones’ lives. For instance, in a committed relationship, you might invest in joint property like a car, house, etc. However, when you're unsure, you can't make such big decisions.
