My Dsis has been with her DP about 5 years. Lived together about 4. He is ok but I've never really warmed to him completely. I have seen his moodiness before and sometimes not agreed with how he acts towards my sister. On the other hand I know my Dsis isn't a saint and can be a bit of a nightmare sometimes.
Just recently she's been saying some things about him that I'm really not happy about. She told him she was going to another city with a girl friend and his reply was your not going anywhere, you're going to help me with my boat. She didn't listen and did go anyway. If she doesn't go to the boat at weekends then he gets in a mood.
She didn't have a job in a while and had no car. She asked him to borrow some money to buy one. He refused. She was in such a state and got to be suicidal, yet he still didn't loan her the money. So my parents did. Yet he will easily loan his friends money, some don't even pay back.
She now just told me that he asked if she was going to the boat tonight. She said no she's tired from work, she said he then hit the back of the sofa and said she was useless. She told me that recently if he doesn't get his own way he will hit a wall or object.
I'm getting a bit concerned. His dad is a bit of a woman hater and makes snide comments to my sister when he's around them.
What should I do? She said she isn't happy but I don't think she will leave him as she wouldn't want to move back to our parents. In also a bit concerned about his behaviour. Ive been in abusive relationships and they have damaged my confidence. I don't want the same for her.
