<human>: Can you give me a shortened version of the text?

So I've been wanting to adopt a dog for a while now. I'm 24, male, and live in a condo in CT. I grew up around boxers and was most familiar with their breed, so when I found a beautiful boxer/pitbull 1 year-old mix I immediately fell in love. My only concern was his high energy levels. I really wasn't sure if I'd be able to handle him.

I ended up thinking about adopting him for 2 weeks. During that time, I asked other dog owners and did some research. No one seemed to regret their decision. I also had him over for a day to see how things would be like. After much thinking and reassurance, I adopted him. I went all out; I bought him a huge bed, new toys, training treats, gates, harness, leashes, a crate, etc.

That was last week, and now I can honestly say I know myself much better now. I love the idea of owning a dog and making a best friend, but I'm not sure if I'm a good match for him. I didn't rush into this decision, but despite my efforts to think this through, I feel like I made a mistake. The amount of time required each day to train him is wearing me thin, and I don't want to resent him for it. I'm at work for 8+ hours a day and it's just me, no SO. I knew this was going to be a big responsibility going in and didn't take it lightly, but still somehow fucked up.

I don't want to send him to a shelter, but instead want to work with a shelter to find him another suitable family/home, and will keep him in my condo until I do. I feel terrible about this, but I feel trapped. It's only been a week since I adopted him. Some would say I should keep trying, others would say to give him to a new home/family before he gets too attached. I partially agree with both sides. Am I making the right decision by wanting to give him to a new home?
<bot>: Adopted a 1 year-old boxer/pitbull mix. Ended up requiring more attention than I anticipated. I fucked up. Should I find him a new family/home?
