Spending time with one's family while studying

Q: Seeking knowledge vs time with family.

I have two semesters left of a 4 year Arabic and Islamic studies program and I am also a 4th year student of the alim course program. I am in my early 30’s married and kids and also full time job. I have been a seeker of knowledge for a few years now and have completed certain ijazas in the past and now attempting to complete the Alim course InshaAllah.

My wife has always supported me, but sometimes I see (feel) that she might be somewhat fed up with me also being busy. I spend a significant amount of time in books research and still with a full time job, also assist a local masjid that is without an imam at times.

I do believe spending valuable time with my family, but I also am fully aware that between continuous studies and full time work (which is needed to support my family) my available time is always at minimal.

Lately a thought has creeped into my head that I should stop my studies and focus on family. Im not unsure if these are whispers of the shaytan or just me being over whelmed. I am thankful for the achievements Allâh swt has allowed for me but on the other hand I feel guilty because the majority of my time is being filtered elsewhere. This is just me venting and asking for advice.

How do I balance? Am I doing too much ?

Breaking up a marriage

Q: If you see the signs of the curse of Allah Ta'ala on someone where they are unable to make duaa and you know he isn't a good person but hides it and pretends, what do the teachings say in breaking up his marriage and removing the wife from this ordeal?

Saying "nikaah khalas" intending that one is married

Q: I am in Saudi Arabia and don’t know Arabic. One day I was talking to a person who didn’t understand much English. He asked me whether I am married or not. I said to him "Yes, I am married" but as he was weak in English so I tend to speak Arabic and I said “nikah khalas”. I found out khalas has many meanings in Arabic such as done/finish/over/complete. But my intention was to say nikah is done/hogaya so will “nikah khalas”  be a word of talaaq or not?

Repenting from illicit relationships

Q: I had love affairs and also fulfilled sexual desires with the girls I had affairs with. But then I got married and have 2 kids. Now I think that if I do it or go for non means, I will be punished in the form of my children doing it. So please give me a solution to the problem. If I marry someone, my parents and my wife's parents will be against me.
