There was a time when Catelynn Lowell and Tyler Baltierra were considered the most stable couple in the Teen Mom franchise.
Sadly, those days are long gone.
Yes, Cate and Tyler are still together ... but barely.
Lowell and Baltierra underwent a trial separation recently, and while both made it clear that they're hoping to save their marriage, it seems the process is taking a tremendous emotional toll.
Take a look:
The Troiubled Couple
Tyler and Catelynn have been enduring quite the rough patch lately -- and they haven't been shy about sharing their struggles with fans.
Tyler and Catelynn have both been diagnosed with mental disorders, and while they're both seeking treatment, the situation has put a strain on their marriage.
Lowell spent much of the past year in an Arizona treatment facility, and many fans accused her of abandoning her family.
Tyler remained supportive throughout Catelynn's many stints in rehab, happily assuming single dad responsibilities.
Taking a Toll
However, it appears that the many ups and downs of the past year have taken a tremendous psychological toll on Tyler.
Through it all, Catelynn has taken most of the blame for the couple's problems.
