"what I should do is ask to see her and not necessarily tell her how I feel"
- Good thinking. Never be ashamed of your feelings, but do show consideration for how others may react.
She may see you as a bit of a stranger at first, and people can change a lot in these years so nothing is assured.
Simply catching up may be a good place to start. Tread warily, Bella, and I wish you every success.
Let me know how you are going if you ever need to talk it through.
