Apart from the fact that I do not believe in fate or that anything is "meant": no, not at all. That is very far from how I look at it.

First, there is no such thing as "the one", not outside the realm of science fiction (I read a novel recently where they scanned everybody's DNA and were thus able to find everyone's perfect match; they also had to do away with all national borders since it was extremely uncommon for the perfect matches to come from the same nation or even the same continent). People fit together more or less well but of course there is not one true match - that's pure romance or satire (as in the book I read).

Second, all those things you describe are pretty unrealistic. Sorry to be all negative but the sooner one stops to expect anything such as understanding or "support" (what does that even mean?) within a relationship, the happier one will be. That certainly applies to me anyway. The way I make my marriage work is by not telling the spouse about mistakes I make unless I really have to, and by taking my problems to T (whose job it is to listen to them and make detached and neutral comments). As for holding and taking care and making things ok.... no, sorry. Not outside the movies. Well, of course H will cook for me when I'm sick, but he does all the cooking anyway And every now and again he'll do something caring, but you can't go around expecting that kind of thing.

Every relationship is of course different though.
