Soon to be Ex-Wife (yeah, I know) has a best friend of 25+ years that has a child and is also going through a divorce.

Lives out of state and wants to move here to be with mother going through cancer treatments. After talking on the phone today, she mentioned if it would be OK if her and her son rented a room in the house I'm looking to buy until they got on their feet. I mentioned that I have NO sexual feelings for her (for reasons she's working on, and else) and that I'm not sure the how the soon to be ex would feel about it.

She told me she is more outgoing about talking through things with me vs my STB Ex. But I talked to her about TRP (which works for Fems regarding the issues she has) and she understands the whole thing.

NO sex or involvement, just a mutual agreement for community living, plus her son likes me and she needs a positive role model for her son.

WTF should I tell her. I like her as a friend but there will NEVER be anything sexual and it will be for about a year.
