Marital problems

Q: I have been having great problems with my wife the last few years. She separated herself from me because of her mother telling her and the last few months she came back and we have been trying to reconcile. She's very disobedient and always fights with me but we have a child so I have tried and tried with her. When we were separated, she and her mother disrespected my mother and my father and now my family don't want me to reconcile because of this. Also she kicked me out of my home three times. I made an agreement with my wife that I will go back and live with her but I want her to sort things out with my parents just an apology to break the ice. My wife refused and just left and has completely cut me off. I want to know is this wrong what I asked of her. I do want to reconcile but know she doesn't want to anymore. I don't know what else to do. My wife only let me see my son the last few months after years and now she is doing the same again. I don't know what to do. Can you please help me.

Calculating missed Salaahs and Fasts

Q: I am 18 years old. Due to my ignorance I am unsure of when I became baaligh. And, therefore I am unsure of how to calculate my missed Salaah and missed fasts. I used to masturbate from a young age, and hence did not have a wet dream after I was the age of 15. I have now given up this act and have seeked for forgiveness in Allah. I feel more confident that I became baaligh due to masturbation, during or past the age of 13. I have come to this conclusion by reflecting on my personal memories, and researched into my internet history by finding the videos/websites I ashamed of viewing to give a better approximation to the time of year I would have became baaligh, which indicates towards me being 13. Therefore, I have more reason to believe that I would have become baaligh during or past the age of 13, but I am unsure if I am being lenient / biased to myself. My only reservation is that I have a vague memory of what I think is think is the discharge of 'mazi' (through masturbation), I am unsure if it was mazi as it was a thin fluid which was discharged in small drops, which did not compare to what I can more vividly remember of mani past the age of 13. Also, because I cannot recall this memory in it's entirety I do not know whether this was between the age of 12-13. And, therefore do not know if should calculate my missed Salaah and fasts from age 12 or not. Do I ignore this doubt and continue to calculate my missed Salaah and fasts from the age of 13? Also, as I am a student, I do not have a lot of money that I can give to charity, and thus I am also wondering what righteous deeds I can perform along side my repentance? Due to me committing these major sins.

Cleaning impurity

Q:

1. Is detergent considered to remove impurities, or only water?

2. How can you go about cleaning an impure toilet seat? Because if you pour water over it, it will undoubtedly go on the floor making the floor impure too.

3. To clean impurity on a hard floor, do you simply pour water over it and wipe clean or must you pour and wipe with a cloth 3 times, squeezing each time?
