Worried about my friend's relationships

[Insertnamehere]

I need an advice about something.............However I think relationships is something you want to share with people that are close to you........

Without intending to sound harsh towards you, but what YOU think about how things should be is completely irrelevant for anyone who is not you.

Not everyone is the same and people are not forced by any law to give an account of their love life to anyone.

There could be a number of reasons why he's not sharing this with people and even is he doesn't have any reason other than not wanting to, you should respect that. You have to respect people's right to keep private what they want. Simple as that.
