If you have reached the point of committing to a "relationship," I would assume you've both made it to where you agree it's "well worth a try". This is good, but only Step 1.
As others have said here, do not be in a hurry to attach yourself to anyone, too soon. Always....ALWAYS be your true self.....and under no circumstances should you begin to become so comfortable and trusting, that you're willing to ignore Big Red Flags. When love is in the air.....it is far too easy to excuse and/or overlook things that, in your heart of hearts, you simply do not agree with or accept as right and proper...per your own personal beliefs. In other words.....do not go overboard to bend for him/her, despite being uncomfortable. Have FUN together and learn to appreciate all aspects of each other's personalities. Give and take...share equally....and pay attention to the "little things."
Meet family and friends, which will help greatly, in getting to know so much more about the person you are with......and how he/she interacts with those closest to him/her....
There's a lot to learn about a new love......be willing to let a relationship evolve with ease and honesty.
