Raidergal - Sound advice as always, from the AB'ers who almost all care about posters in distress, and reach out with help and support.
You need to not look back with a sense of despair and a feeling of opportunities missed.
Opportunities occupy only the future, there is nothing to gain looking back and wishing what might have been - it wasn't, but that doesn't mean that the time as wasted.
Every day, up to and including this one, has given you the experiences that have made you the person you are, and you need to appreciate that person, and not be hard on her for what may have happened in her past.
You must embrace her future, using all that experience and personal understanding to look at what she wants to do moving forward, and start planning for that.
The past you cannot control, or alter, the future, you can, so look forward, and decide what is going to make you happy,and go for that.
Good luck.
