OCD and false humility i.e. pushing a loved one away

First, I am searching for a place/forum where those, in a legal/emotional/romantic relationship can communicate with other people in the same situation.

I have a question for everyone.

My (S)ignificant (O)ther keeps telling me to find someone better than her. Someone that isn't mentally ill. I have looked up on the Net, about people with OCD pushing loved ones' away. I thought I read somewhere that, a loved one allows themselves to be pushed away, to the point of ending a relationship. That the person with OCD will actually feel worse, if the relationship does end. By my nature of being bull-headed n' stubborn(German, Irish, and several brain surgeries), I have repeatedly told her, that there is no one better than her. If I wasn't like that, I probably would have broken up with her years ago.

Also:

1. She will tell me I am better off with a woman that is not mentally ill. Yet she continues to be unwavering in telling me, she loves me. She has never said anything like 'I don't love you anymore'.

2. The only thing I am doing, is saying to her, is that I don't want any other woman.

3. When I actually say to her, that she can go about her life and break up with me, she refuses to break up with me.

The only thing that bothers me a lot, is the lack of communication. The obsessing doesn't bother, even the hoarding doesn't bother me. Just the lack of communication bothers me.

One person said online, what my SO is doing, considering that she has OCD, is 'false humility'. Presuming my SO does exhibit 'false humility', her talking of coming out here is mentally, completely opposite.

Also her recently mentioning that she wanted to join an online support group for one of my congenital health problems. I have actually wanted that for a couple years, but I didn't pressure her about it.
