Not a very convincing argument. Why make a point of telling them you're being loyal if not yet in a relationship? That sounds like an attempt to pry commitment out of them, or emotionally manipulate them into doing the same. If you want to commit then suggest the idea to them and see if they're on board. If not, move on. If it's too early in the relationship then remember that your own chosen abstinence doesn't mean that they owe you the same. Loyalty doesn't come into the equation until you're actually commited.

The answer to other people hurting you isn't to do that stuff to them first, nor to match them to keep it balanced. That's childish bullshit. The answer is to be more cautious, clear in your intentions, and to have a positive life balance so that you're not obsessing over what prospective partners are doing. ... And I guess also to accept that sometimes you will get hurt, and that just sucks.
