How do I get out of this?

I'm currently sat her writing this while my other half is asleep next to me, this feels so wrong. I can't talk to him about these things but I can write it here.

Here's how it is. I'm 22, my other half is older he's 31, we met through work and have been together around 2 1/2 years.

I have anxiety, depression and post and have been through counselling and been on various medication, but nothing has really helped.

I love my other half but I do think feel that he loves me and it's killing me. We don't live together as I still live with my parents and he's jobless currently. We see each other around during once a week and that's it. I'd happily see him more but he only ever seems to suggest a week later, so that's what we do.

What frustrates me is that when we see each other all he wants to do is to have sex. So we rarely do anything else. I don't feel as though this relationship is right and I don't feel like he's the guy I'm supposed to be with forever but I can't talk to him about it thanks to my anxiety. I feel trapped.

How do I talk to him about this without freaking out or chewing myself up? Does anyone have any suggestions?

Thank you. x
