I am happy that you might have found someone that can take Harley and find him a good home. I realize that you must be feeling all kinds of emotions at this time. But I think that you are making a wise choice because you love all 3 of your pets and want them to have a good life. If Harley gets adopeted out you should be able to check on how he is adjusting for awhile and give yourself some piece of mind. I hope all works out well and don't be too hard on yourself because you have done everything in your power to make this work. Who knows might be someone out their that needs Harley more than you do?
