Hello Haures and welcome to R.S.
I am deeply sorry that your mother is now caught up within the romance scammers power and influence over her. And with it being about six months into this contact with her “special someone” I think I can safely say from my own experience that this hook is well and truly set. And given your mothers situation she was already vulnerable to begin with. You are going to have a rough time trying to get through to her, but don't get discouraged. As Igulinka said keep purring on the evidence as you find it. Sooner or later it will start to sink in.
Many victims go through an internal battle between their brains and their hearts during a scam. God knows I sure did. And even though in the beginning the heart wins this battle the brain is still in there speaking it's mind. It's just currently being overridden by the heart for the moment. So just hold in there for your mothers sake. This is going to be extremely hard on you, but please try to stay strong.
As for you job situation I may have an answer for you that may help.
If you live in America, and it sounds like you do. You could try and file an F.M.L.A. Which stands for the Federal Medical Leave Act. You would do this through your human resources department manager.
If you can show documentation that you are the sole carer for your mother, and again it sounds like that is the case. This could be a very possible option for you, but you will have to take this up with your H.R. first to find out for sure.
In short the F.M.L.A. Would entitle you to see to your mothers needs away from work without it being counted against you in any way. This time away from work is unpaid, but your job is protected. And F.M.L.A. Is completely separate from any vacation you may have if any. Though this may depend on your employers policies on the matter.
Bellow I have added a quote from my H.R. Manager when I had asked the question about vacation v/s F.M.L.A. When I had to file one when my wife had a triple bypass surgery and needed me home for a time after coming home. ( Yes she is doing well since then )
Our policy states that while you are on FMLA or STD after 60 days you must then exhaust any paid leave you were entitled to. After you exhaust your leaves your FMLA or STD will continue.
I hope this will be something you can explore to at least ease the stress of your job becoming threatened because of your mothers need. And I wish you luck moving forward with your mother. Just keep in mind that she truly thinks she has found something wonderful to fill her life. And when the truth finally sinks in she is in for a very hard crash afterwards.
My thoughts and prayers will be with you.
