Am I in this relationship because of guilt?

I've been with my partner 5 years. When we met he was in a decent job and took care of himself and was able to buy what he needed and keep a roof over his head.

Fast forward 5 years and I'm supporting us both and my son. He no longer works due to an illness which isn't serious but in his words 'he couldn't hold down a job because he's too ill'. He's never to ill to play computer games all day though. Financially I'm struggling! I'm either at work or college, if I'm not there then I'm home cooking or cleaning.

When it comes to intimacy,it's really lacking. He's always too tired! I have a high sex drive too so this makes me a little infuriated at times.

He's a good dad to my son and he does all the nessicary things to take care of him if I'm working. But as for any housework that's out of the question, he blows his lid if I ask for help.

I just don't know if I'm in love with him anymore. I'm happier being at work. I'm constantly just feeling negative things towards him. We have been trying for a child for 18 months also and nothings happend.

I know the obvious thing would be just to get him to leave as this is my house but I'd feel guilty knowing he would have to move with his parents. And my son adores him. I just know he will never get a job again and I will struggle throughout my life being the only earner. I was bought up in a family where the man is the provider,although mom always worked too. He gets some money from the government but he never gives me anything, he says I get enough money as I get help with housing for his illness.

I just don't know what to do, I'm getting depressed as I just feel trapped and see no happy ending. I'm 30 this year and thought I would have been settled and happy by now.

Even if nobody can offer advice I'm just glad I got this off my chest. Thanks for reading x
