When it's good, it's all good but when it's bad...

I think I'm kind of seeing someone.

I mean, I never really meant it to happen, it just kind of happened. Somewhere inbetween joking about having a pet dog called Bruno and staying round his house all weekend, a month later I find myself in this predicament.

He tells me that he 'worries about me'. He remembers everything I say. He pays attention to me. He listens.

I'm really not used to it. He offered me a lift home in his car the other day and I refused. Things like that make me realise that I have become far too independent over the last three years- refusing help, becoming too self-reliant, never putting myself in positions where I would feel I 'owed' them something.

And so what's wrong? It all sounds good, right? Well, I didn't really mean for it to happen. I can't see myself spending the rest of my life with him but we get on really well. So am I self-sabotaging? I've already pulled away and told him that it wasn't what I wanted, but then we just ended up back together, on his sofa laughing about having an imaginary pet dog called Bruno and staying round his house all weekend.

What do I do?
