Not entertaining drug addicts

Q: If a drug addict live with us and he steals our things and just make life so difficult for us, is it wrong of me to not give that person food? We used to give before, for years we just looked pass it but now I stopped and I feel so bad about it. Will Allah be displeased with me if I don't want to give anymore? If drug addicts ask for food is it also wrong to refuse them after we know that they spend their money on drugs and depend on the community to help them with food. I love to give and used to give anyone that came at my door but the drug addicts are persistent.

Tauwbah

Q: I have a question regarding the hereafter. I currently know that I made mistakes in my past where I've eavesdropped and seen in other people's houses in the past. I don't ever intend to do it again but I have no idea on how to contact all the people that I have done this to. (It's impossible for me to find some random people). How can I resolve this issue and does Allah forgive major sins on the day of qiyamah and can he forgive my sin on that day when it comes to doing wrong to others like my self. I have a bad feeling that I'm going to get punished indefinitely and I all I want to do is resolve this issue.

Husband telling the wife "It's over"

Q: On the 9th of December my husband told me its over over whatsapp but after that we slept together and told me he didn't mean what he said and then again he told me "I'm done" and again over whatsapp that was on the 3rd of January and then my mum asked him are you and my daughter finished now, so he said yes. Does this mean we are divorced or not?
