Before you can find love again, you first of all MUST believe that your soul mate is definitely out there somewhere in the world, waiting to find you. Then you have to be very clear about what that prospective partner will look like and be like.
What you need to do is sit down somewhere quiet, with no distractions and REALLY think about your ideal partner. Think about what values they should have, their personality, their interests, their sense of humour, and their appearance.
This will probably take some time (even weeks or months) to truly work out who your ideal partner should be… SO BE IT. No matter how long it takes, it’s worth it to find your true love rather than another person who isn’t going to work out. If you’re not very clear on who you are looking for, you will keep getting partners that do not suit you, and the relationships will ultimately fail.
