My sister lives in Switzerland. She only got married because she needed a visa to stay with her then boyfriend but she was never fully convinced by him nor his family. She was 38 and they had been together for a while so maybe she thought she had wasted her best years, who knows! Fast forward and now they're both unemployed, they have an almost 3yo, he's very short tempered (she's a nightmare to be around and thus why don't talk to her and only know about this via our DM). They keep getting on regular fights about everything, mostly that given that she doesn't work she doesn't look after flat and son properly (but he's unemployed too). They almost called the police the other day but they didn't. I think my should just leave, but she's concerned he'll take primary custody and won't get a visa to raise their son in Switzerland. I wish I could any decent advice, but I really don't know what to tell her.
