My ex’s family were in this same position. His mom used to give him $ here and there that’s why he kept asking and asking over and over again. He knew he could break her down and she’d give him $ just so he wouldn’t keep calling and calling. She finally learned not to answer the phone unless she knew she was in a good standing strong emotional spot.
Al-anon can help you build emotionally strong boundaries and support to help you stick to them.
This is an awful situation for you and I am so sorry and wish you did not have to deal with such stress.
Keep posting, lots of others have been where you are right now. Please give al-anon a try, it certainly can’t hurt!!!
((hugs))
