First of all, I don't believe in "destiny." I think in order to make things happen in this world we have to go out and do something, rather than sit around and wait for something "destined" to us to happen. And with relationships, I am pretty sure that, most times, you need to go out there and meet someone in order for a relationship to occur!
In your chart you have Neptune (spirituality, also idealization) focused in the 7th house (relationships) square (energy needs to be combined with) Venus (relationships), indicating you tend to idealize relationsips, always looking for the "perfect" relationship...which is never the relationship you are in. You need to understand that there is no "perfect" relationship...every relationships takes time and effort from BOTH people in the relationship to make it work.
So go out there and meet people, not expecting them to be "perfect" but instead expecting them to be "human"...people who have some strong points and some flaws, but who are getting along in life the best they can. Then find someone of those people whom you think you could work with to create a relationship and who wants to work at creating a relationship...and see where the relationship goes! Don't expect perfection, but, if the relationship becomes very difficult for you both, break it off and look for a new relationship with someone else. For that is how all relationships work, trying things out with another person and trying to make it work!
