Creating happy and healthy relationships does take work and I will not disagree with the beliefs and thoughts of the old world- it does take patience and love to foster good and lasting relationships.
Yet there is something that Law of Attraction enthusiasts know that others may not know and/or actively practice, and that is -
'Like Attracts Like'.
Law of Attraction enthusiasts know that thoughts and ideas create the situation first, setting the stage for appropriate action to happen.
If your thoughts and ideas about a person is stuck in the past, then that is what you see more of, a repeat of the past.
Constantly visiting situations 'as they were' as opposed to 'how they could be' creates a cycle of the same to be experienced. Things change, people change, and situations change. Even if someone has closed a door on a relationship, it is still possible to recover that relationship if that is what you truly want. This is how powerful the Law of Attraction is.
What needs to open up is the door of love and positive expectations in your mind, and since everyone and everything is energy, that person will flow in through your door, just like water. The nature of water is to flow, if there is a way for the water to flow, i.e., it is not walled in on all sides. If water is walled up on all sides, it cannot flow, except to overflow and flood if the level of water gets too high. But if water is allowed to flow in a certain direction (that you monitor with your desires and thoughts) that water will flow in the direction provided for it to flow.
The same with a person's energy. You can have it flow towards you, if you exercise the right thoughts, driven from the right beliefs that can make it happen. The main difference between forcing something to happen and having it happen is that you provide the stage for whatever you want to see happen, to happen. You don't make it happen forcibly. It just happens. This is Creation Law.
So knowing this, how will you put it to work?
Start with watching your thoughts and emotions. How are you feeling when you think of certain people? Your body does not lie and you will know how a person makes you feel.
Next, knowing how you feel, rearrange your thoughts and beliefs and focus on any feeling of relief that you may now experience from the changed thoughts.
Love is what we are here to experience and it includes love for people, places, things, and this life and world. There is no shame in enjoying this love because that is what you are for. What you create is your choice.
But what you require love and patience for most, is not the relationship itself, but yourself.
You need to have love and patience with/for yourself. You need to give yourself the chance of hope and active possibility that things can work out, for you. This is about you, and not the other person. When things work well for you, then people just become your friends on the journey.
Everything starts from you and and as your personal luck factor changes, everything changes.
Lots of love.
