Assalamu Alaikum - My dad may have messed up a rishta meeting

Assalamu Alaikum. My dad isn’t great with social situations - he has a big ego and sometimes says things that aren’t appropriate. When he met a prospective family recently, he made a few awkward comments that made the whole meeting strange. I don’t think he meant harm, he just doesn’t always realise how his words land. It came off like he was trying to sound very wise but ended up sounding a bit clueless instead. What made it worse is he dominated every conversation and turned it into his own show, so nobody else could get a word in. I was so embarrassed. Before that meeting the young man seemed genuinely interested, but afterwards he seemed unsure about continuing. I know first impressions matter, but it’s frustrating when something like that is totally out of your control. On top of that, my dad has cut ties with many relatives, even my mum’s side, so I don’t have uncles or aunts who could step in to help smooth things over or mediate in a moment like this. I’m the eldest daughter, and I didn’t expect him to be so unpredictable. My younger brother is more stable but he’s away for work, so I was left to handle it on my own. Has anyone else dealt with a parent’s behaviour making a rishta or marriage talks difficult? How did you handle it, and are there any polite, Islamic ways I could try to repair the situation or reassure the family involved?
