Thank you all for your advice and perspective. Ultimately, I ended up taking job #2, and as soon as I made the decision a huge weight was lifted, and it feels like the right move in my gut. I handled my departure as professionally as I could. When I told my manager at job #1 that I was leaving, she said she was disappointed but much to my surprise, she also said that if she were in my shoes and if she thought job #2 was the better long term fit, she'd probably make the same move. My last day at job #1 was yesterday and my first day at job #2 is Monday! Ironically, another job I was interviewing for but pulled my name out of when I got job #1, I just found out that the hiring manger who I would have reported to, left for another job...and I can guarantee that if I had taken that job, that the manager wouldn't have given much thought to me coming on board and the committment he made to me.
