It sounds like you answered your own question. There's no magic about staying in a relationship that doesn't suit either person. It just creates more pain down the road when you two REALLY get sick of each other.
Why do you want to stay with him if you are not compatible?

I had to edit this, in spite of knowing better than waking up and writing something like this- I still do it, then regret it later. I wasn't really awake and my thoughts sound so judgy.
Breakups suck, I am a rip the band-aid off kind of person because I have stuck with someone who I really shouldn't have for years
There was such an emotional toll. I wouldn't want someone else to go through that!
You really don't need anyone else to tell you what to do, ultimately it's your choice. But, if you want confirmation that this sounds unhealthy, then yes. In my opinion it does not seem like a good relationship.
