Of course it is just an opinion, but I too think you made the right decision. An adoption that didn't work out would not be in the best interest of Lilli, Drake or you. We all have to face the limitations of time, money, strength, as well as the dynamics of relationships between animals. When I was younger, I took on more than I could handle at a time I was not in the best of health. I look back at that time with regret. Better judgement and decisions could and should have been made. I commend you for taking the time to think this through and not act on impulse. Believe me, I know how hard that can be.
