I've been dating someone, who I'd known for some years, and knew had had mental health problems, for a few months. I've gradually come to realise that he isn't who he says he is: that some-maybe all-of the things he tells me about himself just aren't true.

I have no one to talk to. I haven't met his family- there's always been an excuse why I can't travel to him, or, because he travels for work, why he's near me anyway. And my friends and family-well-I'm not sure there's anyone I can trust not to look down on me for being made a fool of.

The thing is, he's becoming severely depressed. A couple of nights ago he told me that he was spending the weekend with his old professor, who would be able to help him. I wish I were sure this professor even exists...

I told him that I didn't want to be part of the problem: that I knew some of the stories he'd told me weren't real. He admitted this, and I didn't push it. Maybe I should have done. I'm so scared of hurting him that I'm ending up hurting myself (I have disordered eating; it had been under control for a year before we started dating and and I've now lost control of it completely).

I don't know who he is, and I feel like I've got no way of finding out. And yet I love the person he is when he's with me.

I want to support him, but I don't know how. And I don't know if I'm strong enough. And I don't know how much of what he's told me I can stand to be unreal before it feels as if everything is a lie.

I'm sure it all sounds a bit childish to those of you who live with problems every day. But I just don't know what to do...
