It seems almost certain that this is going to be another case where we start with the general rule (that there IS no absolute rule that applies to everyone) and then analyse this as a case of particular importance because of the amount of pain and pleasure that can come from it. Surely it (hyper-romanticized love, anyway) also fits in a category such as "intoxication" which is often, but not always presumably, going to be a bad idea. But "marriage" doesn't have to be based on intoxication, and we'd have to know tons of variables to reach a specific conclusion in a particular case.
And we KNOW that Epicurus directed in his will that Metrodorus' daughter be married - there is even an academic article citing that point somewhere. So in this case it might be that all of them are erring in not making it clear that this too is a generalization rather than a rule. I would think that if possible to a good match, Epicurus would say that it is desirable, but to be cautious because of the risk.
Same thing with children, which might be even riskier, but has great rewards if done right. Probably need a separate thread on that at some point - years ago there was a long discussion of the relative merits and demerits of "childlessness"
