Does she live alone? Does she have children? Did she give a reason?

These are valid questions you do not address.

This is still suspicious behavior even if her parents won't allow visitors, so ask her what the deal is. And if you can somehow get her address, than check things out on your own and see if she married or has a boyfriend.

She has a boyfriend or husband. You're a side piece.

8 months and you still haven't been to her house? Maybe because her husband and children are at her house.
