I am glad you are feeling more enthusiastic about your future.
The Doctor came into your life to show you there are nice men out there, you were attracted to his vibrant energy and felt his kindness.
Spirit will send us a person they know we need to help us rise above any kind of hurt or abuse we have had in our past( or any time) that we need to experience and Feel as being kinder person.
It is to show you that you can have a happy loving r/ship with the right person
It is not unusual for us to have a crush on a person who we feel attracted to because of their good energy and kindness if we have never been treated well by a male, or experienced what it feels like to be treated with kindness and love by a male Father figure but of course if that person is married then we need to respect that.
Leave it up to Divine timing to bring to you the kind of person that will be right for you as a partner, don't worry about Who, When, Where, that is all taken care of by the Universe they place us where we need to be for that meeting to take place.
First you need to give yourself self love, self confidence, and feel and be happy for yourself within when we do that for ourselves we then know we can make the right choices when we do meet new a potential partner knowing what we do want over what we don't want.
When we are vulnerable with our emotions and want kindness and love in our love we need to be careful not attract the wrong kind of person who will take advantage of any vulnerable feelings we show as being desperate.
So please do all the above for yourself don't just go out blindly if you are feeling vulnerable emotionally hoping the first male you meet is the one as many do and get very hurt give yourself time to know a person our feelings our gut feelings are our warning signs they let us know if something doesn't feel right and if it doesn't it usually isnt .
You will be fine just know it is all about Divine Timing be happy, get out there and enjoy life do fun things with happy positive friends and it will happen for you when you least expect it you have much to look forward to.
