The fact that Tyler is talking about it, and not just doing it is a good sign. I do not know if the two of them will make it through this time, separate, or whatever, but talking about things is always good. Catelynn is going to be insecure no matter if he talks or not, and she certainly is going to be better off if he talks and not acts. I truly think that eventually they will take a break, and Tyler is very mature and will find a girl or some girls and will realize that having a bond is much more important than random hook-ups. Whether he will need to go that far to figure this out is anyone's guess at this point.
