Spending time with one's wife

Q: I wanted to ask something about relationship issues. My husband is very strictly religious and he reads lots of Islamic books through the whole day in his free time. Even at night I tell him to sleep early, at least at 12 o clock in the night but he reads the seerah of prophet Sallallahu Alayhi Wasallam and completes all the amal of zikr which is done under his shaykh. Then he goes to sleep at 3 or 4 am. I sometimes get upset about that. He doesn't give some of his free time to me and if I say anything he says that we must think of the aakhira, not the worldly life. Sometimes I comfort myself that what he's doing is to please Allah, so I don't bother him. But I want to know that what he's doing is it more rewardable than having free time with his wife and sleeping early with his wife?

Difficulty getting married

Q: I am now 31 years yet can not find a groom. Actually I missed many opportunities now I regret that though I know that was Allah's decree. Now I feel too restless. No inner peace of mind. How can I remove my stress by dua? How can I convince Allah for getting married very soon?

Surrogacy

Q: My question is that if a Muslim man has two wifes and one of them has womb cancer which means that she can't carry a pregnancy. Could the other wife carry the pregnancy for example like a surrogate would if she wishes to?
