I agree, C & T do seem very "stuck". They also make their income by giving speeches about their experience with adoption. At this point I feel like the adoption (Carly) is the only thing really keeping them together (other than Tyler being scared of hurting Catelynn by doing the right thing in the long run and breaking up with her). She seems very clingy and he seems unhappy in the relationship and should not be leading her to believe they will get married when he actually doesn't want to.
