While he may not have said it completely, I think Health meant that it is a good thing that SG did not get further into the relationship, get married, have children, and have years invested into something that was not the right thing for her. I don’t think it’s a matter of that other people have harder situations, but that SHE herself could have been in a much harder situation. I’m not suggesting she should be grateful to be suffering, but, by keeping things in perspective, she will hopefully find her bashert soon and move on with a clean slate.
SG, I think you asked about what does “bashert” mean. I was under the impression that the meaning in most cases is “meant to be”, that Hashem means this is what is supposed to happen. So in this case, your bashert is the one who is meant to be your partner in life. I have also heard of the concept that we have more than one bashert depending on where we are holding in our lives, and I’m not sure how that goes along with the concept of bechira. Maybe bechira has only to do with choosing to do mitzvos or aveiros, maybe someone with more hashkafa can give some more insight.
Hatzlacha getting through your nisayon.
