Sometimes I feel like a broken record. I am not sure if I have shared this with the two of you or not. However, the best way to manage the Law of Attraction is to maintain an Attitude of Gratitude. Mr. Positive, you did it with the misunderstanding with your mom and you can do it with your ex. There are two ways to view what is happening. One - The Universe gives you EXACTLY what you ask for. So, if this ex does not have EVERY quality that you desire in a mate, you will not be together again. The Universe will NOT let you settle.
The second is this, if you feel this person IS everything you desire and you know this to be true, then you MUST be grateful for them as though they are already with you. I have already seen this work in this forum. Be grateful for the person as though he/she is already by your side. Be grateful for his/her love and support. Feel the warmth, the passion. Frustration, feeling lack of, etc will only attract more frustration and feelings of lack.
The transition doesn't occur overnight. Many times "events" need to take place in order for this person to show up as you desire in your reality. The Universe will make the changes you just need to sit and be grateful.
Hope that helps!
