Funny because I had my mother live with me several times in the past when she needed someone to take care of her, but it was never on issue with the guys I've dated or were in a relationship with! quite the contrary; a guy who live with a parent, and take good care of them, in my opinion and personal experience, have the potential to be a great partner. A loving and caring son usually makes a better lover and life partner in my experience. Furthermore just because you have a parent living with you it doesn't make you a mama's boy, or not capable to make decisions on your own. .
Dear Leandro, so nice to see you do a post again. They always give me pleasure. 
Your scenario is somewhat a reverse of the point some guys are making here, but nevertheless a good one in its own right. And I suppose some straight guys take elderly parents in, too, it's not just gays who would do that.
My husband did so when his own mother was in her 90s, before I met him. She wasn't seriously infirm, even at that age, but still needed some care-taking, especially since she no longer chose to drive.
He tells me she was a pistol. And loved to be around gay guys. Went to gay clubs with him, parties at gay homes, she became a regular on the gay scene. A whole new life for her, and she was very popular, as his friends who knew her tell me. She even had her favorite gay bartenders that she always wanted to see. Even though all she drank was Shirley Temples.
Point is, the scenario you describe is very possible. And I think the son's (or daugher's) role should be admired. A true mark of family love & support.
My dear friend my mother nor anyone in my family have never had issues with who I choose to love! that said I am perfectly aware there are many gay men who have not lived this family scenarios. But I can assure you there is also a lot of gay men who share my experience as well.
I was raised by a mother who did not remarried, even thou she could have at the time when my parents separated. But she chose to educate and raised her children on her own instead. My mother worked very hard and sacrificed her personal life for the well being of my siblings and I. Now that she is getting closer to being eighty, and decided to no longer drive, I feel is my duty to be there for her whenever she needs someone to help her or drive her around, as she did when my siblings and I were younger.
I am very upfront about my mother's needs to my dates and every relationship I've being in, and the majority have never had an issue with that. I pay my own bills, home mortgage, and expenses, even thou I am always there for my mother whenever she needs me, and I have never said no to her when she does over a date! I am far from being a mama's boy or needy for that matter. That said I don't understand why a single child, straight, gay, or bi will feel ashamed for living or being part of their parent's life at their old age. Looking after my elderly mother have taught me a lot about love and compassion, two things I can never live without!
Is always being a pleasure interacting with you over the years, and seeing how much you've grown as a human being. You are also an inspiration to me and many others on this site, so thank you from the bottom of my heart.
