It all boils down to how you are feeling about yourself. You know what you want and the Universe knows what you want as well. You need to become a vibrational match to that. So start now by paying attention to your positive qualities, and affirming many times a day that YOU FEEL GOOD ABOUT YOURSELF. Be very diligent with this too (aim for 1000 times a day) and you will become that vibrational match. The Universe will then send you the ideal older women and you can choose which one you would like to be in a relationship with.
You also say that manifesting a relationship is not easy, and that too is a belief which is creating your reality.
