Need advice : Divorced mother keeps talking with young unemployed guys

Hello guys, I’ve been going through something, it has been very difficult for me to assess and see what to do. Basically, my mother who is close to 50, is divorced. She has a very bad problem where she likes talking to guys. Previously, it used to be multiple guys at once, but nowadays its just one. What’s astonishing is that she somehow finds all these younger 20-25 aged guys, talks to them continuously and somehow these guys are even ready to marry her. Problem is, they are all very young, jobless, financially very weak relatively, and also their own families are unaware. No matter how much i try to convince her to stop doing this she just doesn’t listen. In her mind she believes she’s doing nothing wrong, although, it is affecting the environment of our house. I try to say to her if she wants we could even try finding an actual decent guy for her but she doesn’t care. I get so much pissed off whenever i see her talking, sometimes its late at night, sometimes its earlier in the morning. And they are talking for like hours or something, i mean what the hell are they even talking about. One time, i found her phone, the guy she is currently talking to was calling her, i rejected his call. He called again, and then again and i kept rejecting it. I actually started counting how many times he was going to do it, and it was more than 10. I mean what are these people. I legit don’t understand what to do, at the end she is my mother but this is something which is really bothering us. My younger brother has just accepted it and just tries to ignore her behaviour, however, i get really bothered. Whenever I leave for my job, and i see her like this, it just ruins my day.

I don’t know what to do. She talks to those types of guys who post tiktok style whatsapp status and have snapchat filter like DPs, i absolutely hate it. Normally what happens is that parents try to control their children, monitor their screen time, monitor whenever they go out. But yahan pr to ulta hi hisaab ha bhai. I have to look after her,monitor her so she doesn’t end up doing anything which could hurt her or us. I’m the eldest sibling at home, I manage everything, I have two other sisters who live abroad, but they don’t really care much, they have also just accepted it. They also don’t understand how the situation is like over here.

I’m trying to look for some outside perspective here, how do I approach this. She’s also not looking forward to get married right now, since marriage could confine her to pakistan and meanwhile me and my brother are trying to work to move overseas and join our sisters. Its all messed up and confusing.
