Hello miragex, it's nice to meet you, welcome to psych central.
It sounds like you really care about this woman. What first comes to mind for me is that maybe you ought to ask yourself some important questions about this situation. Like, is this kind of relationship really healthy for this woman? She is having to live her love life in secret. Is this relationship healthy for you? Are you willing to continue this relationship for a long time? There are probably more questions that would be helpful but you get the general idea, when you are in doubt of something it is best to ask yourself the hard questions and answer them honestly.
I am sending you some hugs
