The first major sign in knowing if somebody is right for you is that they will bring joy and happiness into your life and not misery and you will bring the same thing into their life. They will bring pleasant companionship and not confusion. You will not have to compete for their attention and affection.
When they are not around you miss them a lot, and they tell you that they miss you a lot. You talk on the phone regularly and send loving text messages through out the day. You never go a day with out seeing each other or talking on the phone.
You can see and hear the excitement they have for you. They talk to you and about you like you are the love of their life. They always remember anniversary dates for your first time that you did anything together.
When you are together you are always hand in hand. You have your arms around each other when in public. You don't mind showing public affection. You both love to be seen together and are pleased with each other. They will want to be with you as much as possible. Why? Because they find great joy and peace in your presence.
They love your company and in their eyes you are their dream come true. You can see all of this in their eyes, their expressions and actions and you can hear it in their words.
You just know, on the inside that they are for you and they prove it to you everyday. You are their choice, they have chosen you and they will do everything they can to prove it. This applies to the male and female when the attraction is genuine and mutual.
You don't have to convince, bribe or beg for them to go places with you or do things with you. Why? Because they are always ready to do anything with you because they enjoy your company.
In fact they are always asking you to go places and do things with them. The offer is always open for you to share in the things that they like to do and be a part of their life. In other words you're always included and you never have to worm your way in just to be with them.
So if a person's right for you, you will both be inseparable and you will be each others best friend. And you will be happy and peaceful being together no matter where you're at or what you are doing.
