Most of the time it’s not the person you miss, it’s the feelings and moments you had when you were with them. Don’t let a sweet moment and wonderful feelings you had in time pass tie you down to a person or relationship that has turned unhealthy, toxic or abusive when the person gets comfortable enough with you to start showing their true color.
Never change who you are(in a bad way) for someone’s approval/acceptance. Anyone that truly love you will accept and appreciate who you are and will never force you to do what you don’t want to do or what can have a negative repercussions on your future. Be proud of who you are in a positive way and only choose to be with people who see value in you and appreciate you for who you are.
You can’t have a perfect relationship because you are not perfect and nobody is. However, you can have a great relationship(a healthy and loving relationship). A great relationship begins when partners learn to appreciate their similarities(what they have in common) and respect their differences(what makes them unique as individuals).
