what does unlucky union mean?

It says this all the time on cafeastrology and I'm confused as to what it means because it's come up with three of my love interests.Like what the hell? Someone tell me pleasee?

From what I took it as, was a not very good pairing

Well I'll say the aspect. The aspect was saturn square neptune so maybe give me insight on that

Here's what I saw about that aspect:

The square between Saturn-Neptune in the Synastry chart can indicate a karmic lover relationship, but the lovers have not usually lost one another through their love, that is, their relationship didn't cause or contribute to the death of one or both partners as can be the case with the Saturn-Neptune opposition in a karmic house touching a planet or light in both individual nativities. The square more often indicates that there were difficult circumstances in the past that the two individuals failed to handle appropriately and they will once again face a similar situation together. Their incompetence may have cost lives, particularly if they were involved in the medical profession or were military leaders. This configuration can appear when both partners need to work toward a goal that will benefit mankind. It can become a driving force behind a team dedicated to helping others. The square will often be strong enough to hold the two people together if they are able to focus the energy outside the relationship rather than within it. The fear that lingers so deeply with the opposition could manifest within the relationship with the Saturn-Neptune square, but it isn't likely to be as strong nor focused within the relationship. For instance, meeting the other person could bring up unknown fears and insecurities within each individual, but they will not be fearful of the other person. Instead, they may come to lean on the other to offer support and help them overcome the new fears as they develop. Fear of professional success or health maladies may be brought to the forefront through the connection. For instance, one partner may be scared to take a risk in order to make more money or gain prestige in his or her profession while the other partner develops allergies or begins to worry excessively about cancer or another terrible disease.
