Are you truly authentic?

So I have a question and there really isn’t a right or wrong answer..so here it goes! When you are in a relationship are you true to yourself in who you are in that relationship? Often at times we see relationships that are a façade for social media or just in general want the public to envy and want they have, Truth of the matter is no relationship is perfect and I can tell you from my own perspective that mine isn’t all peaches and cream because we are all human. I can tell you that I am my true self with my husband. I’m loud, I very open and blunt, I don’t hold back because there isn't a reason to be. I love the transparency because I can be myself without judgement and vice versa. Why do you think people portray this image and why is it so difficult for people to be this way in a relationship. Is it because of fear that you may be afraid of what your partner may think or maybe you are not sure yourself on what you want. Could it be that you may be in love with the idea of what your relationship should be like and fear the unknown. Would love to hear your thoughts on this. xoxo
