Sadly OP didn’t come to the thread. I hope everything is ok with her and her situation. I am with MsLady on this. Something is off. Unavailable men like to use excuses like kids or jobs or moms or hobbies to avoid spending time with a woman.

I’ve also met men and women who claim to live with their parents because they are being caregivers. In reality they live with their parents because they can’t afford to be on their own (understandable in OPs situation of having illness and temporarily living at home due to covid). brothers are caregivers and both are not on their own? Hhmm.

I also doubt mother restricts his screen time (how would she even know when he is on the phone if he is in his own bedroom for example?) .

The guy is not available for relationship with OP and mom is a very good excuse. More likely that he wants to keep his distance and avoid commitment and would rather do something else than communicate to a girlfriend. Attraction to unavailable men is real and not particularly easy to overcome but it’s doable.
