Repenting for one's sins

Q: For repentance you need to feel guilty about the sin you committed. I don't feel guilty in my heart, can I verbally say that I feel guilty about the sin, would that be enough? I can say verbally "I regret doing the sin, I shouldn't have done the sin" would that be enough?

Attending the da'wat of someone whose major income is from haraam

Q: My question is that some of my relatives live in UK where they work in different sections such as the sale and making of Alcohol. They send their
income to Pakistan. That money they use for their house hold usage. Now they are getting their daughter married and when we go to meet her, we are invited for dinner. The problem is that is their income is halaal and we can eat food or other things from their home or not? Is it halaal for us, because we know about their income is from haram sources. In uk it is halal but in Pakistan it is Haraam?
