PLEASE HELP

I am horrible at sending important texts, I just don’t know how to use my words properly. I’m moving in with my friend this summer and I want to ask her how she would feel if my man moved into my room with me but I don’t want to come off rude or intruding. He would be paying rent as well so it would actually make it cheaper for everyone. I just don’t want her to feel uncomfortable. One other person is going to be staying in the house as well so it wouldn’t just be us and her.
