Un motivated bf ?

So my partner and I have been together over 10 years. I'm now in my 30s and I find him so unmotivated. He isn't working due to being on sickness . But he sleeps in until 11am. I'm up before 8am with our son and he's sleeping in, while I do everything . Every morning. He either is up late playing video games or been up drinking. I'm getting over it and i have found that I myself have become lazy and unmotivated. Now and then I get inspired to create a business but I never can follow through its like I sink back to my dark hole.

My partner is a nice person and is great with our son. But I am doing all the feeding, changing, sleeping and I am feeling so run down.

I get annoyed with his laziness and lack of desire to make something of him self.

I also do not find any sexual chemistry..and I find it annoying having to have sex . He doesn't look after himself and so I find him unhealthy

Anyone else been through this
