['It is hard to make a decision to take a new job when you have been with one employer for a long time.', 'I agree. Do you find yourself in that situation right now?', 'Yes, I feel like I need new experiences but I feel a sense of loyalty to my current employer.']
That's very kind of you to be so considerate. Hopefully the right choice will make itself obvious to you in the near future.
I have been at my job for over 10 years and though I feel like I could use some additional experiences, I also feel a sense of loyalty to my current company.
