This is one important thing to watch out for when in a relationship. If he is super sweet to you but constantly ragging on your parents or friends, you need to cut them loose. Respect must be given not only you but also to those whom you love. As respect is the most important factor to keep your relationship alive.
There is no doubt about him as he trusts you completely. You are both capable of doing your own things without the other becoming irrationally jealous, suspicious, or angry. Remember it is trust that makes a relationship healthy, without trust love cannot last.
You are lovers and best friends at the same time. You fully know each other, no secrets are hidden between the two of you. You talk like best friends, play like kids, argue like a couple and protect each other like siblings.
As people say “Honesty is the best policy” and that’s what you both do. You are not afraid to show your true nature with him --- your craziness, sense of humour, even the awkward things you do, he doesn’t mind those things. He enjoys your company. He loves to see real you and the best part is you feel comfortable by knowing it.
