You have been with her for two years now and you've told us that you don't trust her, you particularly don't trust her to speak to a male friend, you could not resist going through her phone, you think it is a major issue for her to be on sc so she can be in touch with her family, you need to look for reasons to stay.

Why are you in a relationship with her?

In previous relationships of yours, to what extent were there similar issues of trust and insecurity?
