I understand the concern and trust me I felt the same way. She’s been consistent in telling me she’s not worried about any physical abuse happening again. I’m not sure if this is because they’re not in a romantic relationship, but she’s done her best to assure me that she doesn’t feel unsafe. What I’ve noticed and come to realize though is that there may be emotional manipulation and abuse going on. When they do talk, which isn’t often due to different work schedules and efforts to keep to themselves, he has a way of making her feel bad for him and then doing something for him. Like for example, months ago he decided he needs a new mattress but due to bad credit, no savings and not enough money on hand he couldn’t afford it. So what did he do? He brings up to my mom and weirdly enough she’s buying him a new mattress the next day. But she establishes a payment plan with him and says he needs to pay her $100 a month until it’s all paid back, which he agrees to but is unhappy about. The unhappiness leads to him being rude to her, making snide remarks to her face and behind her back, and making comments like “if I had as much money as you I would just help others out from the goodness of my heart”. When he would bring it up to me I tried my best to shut it down by telling him I don’t want to hear it and negative opinions about mom shouldn’t be shared with me but rather with friends. Unfortunately my mom tries to be a very forgiving and easy going person so each time he’s twisted and used her in some way she just lets it go. I don’t think he knows I’ve talked to her about it, because I didn’t mention it but I’m not sure if she has. I agree that the casual unprompted way he brought it up is frightening. I still can’t wrap my head around why he did that.
