Wouldn't you have inquired and been pondering about things if he were to say nothing, and just ignored you?
You don't view this as him possibly being respectful??
You not wanting to communicate until the meeting may seem like you're playing games to him.
Did he say other things to make you question whether he is oversharing or not???
From what you posted, it doesn't seem to be oversharing. He said basic things. He is taking care of a sick mother. .
Do you just not connect to people emotionally or is it that people or maybe just men sharing things such as emotions...make you uncomfortable??
Is it that you just don't want to envision a male taking care of a sick mother, are you someone who feels that this makes him "weak"??
Maybe he just wanted to be upfront and honest with you about him taking care of his mother ..perhaps often.. maybe previous people thought they could handle it but couldn't.
Perhaps it may be best to move on..if he has taken on a caregiver role in his mother's life, she will be his top priority, and he won't have time for you...if that's the case...maybe he should refrain from trying to date seriously.
You don't know this man, and if you proceed. . This may be a red flag.. perhaps he is thinking about introducing you to his mother rather quickly and perhaps in a rush to incorporate someone into his life, to take over the caregiver role.
You are not obligated to ask or inquiry about his mother's health. If you are feeling uncomfortable with the notion of that...or feeling pressured to do so, it is best to end things and move on.
It's okay if you'd rather not hear about sickness, illness, and other things you may find depressing. . It may put a damper on your mental health...especially if you are struggling, or have made progress towards a recovery.
Not everyone wants to hear these things.
If you feel like you inquiring about her health will lead to more oversharing and if you are feeling like it will impact your mental health....it's best to move on..
After all it's holiday season and almost Christmas (if you participate in these things).. perhaps you are feeling happy and joyous..
Don't let him damper your mood.
