All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His Slave and Messenger.
You did well by forbidding your fiancé from expressing his love and affection for you then because you were still a non-mahram woman to him; please refer to fatwa 86143. In fact, such expressions of love and affection should be exchanged after concluding the marriage contract; it is odd that this man does not express his love and affection for his wife while it is permissible and was keen on doing so when it was prohibited! This husband is advised to strive in pleasing his wife so as to strengthen their marriage and foster mutual affection. Husbands should follow the example of the Prophet in this regard. Allaah, The Exalted, says (what means): {There has certainly been for you in the Messenger of Allaah an excellent pattern for anyone whose hope is in Allaah and the Last Day and (who) remembers Allaah often.} [Quran 33:21] Please refer to fataawa 86618 and 88304.
It is incumbent on the husband to provide for his wife's accommodation, food, and clothes; however, he should not settle for that as long as he can afford to do more. He should treat her kindly and provide her with a comfortable lifestyle for she is his wife and the mother of his children. Allaah, The Exalted, says (what means): {Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allaah has given him. Allaah does not charge a soul except (according to) what He has given it. Allaah will bring about, after hardship, ease.} [Quran 65:7]
As long as your husband provides you with your needs, then you should not mind him spending on his family as he is obliged to show kindness to them and this is a form of maintaining the ties of kinship. We remind you that when the wife encourages her husband to show kindness to his family, this may endear her to him and his family.
If the case is as you described and he resents your family and verbally abuses your dead mother, then this is a grave evil deed that may lead to breaking the ties of kinship. The Islamic sharee'ah forbids verbally abusing the dead. 'Aa’ishah narrated that the Prophet said, "Do not speak ill of the dead for they have already seen the result of their deeds." [Al-Bukhari] This also incurs a graver evil that is causing harm to the living; Ibn 'Abbaas reported that the Prophet said, "Do not vilify the dead (and) by that harm the living." [Al-Haakim who graded it Saheeh (sound) and Ath-Thahabi agreed]
You bear no sin for harboring hatred towards him for his evil behavior; however, it is impermissible for you to not talk to him or deny him any of his rights. You are advised to be as patient as you can, to implore Allaah to rectify him, to kindly advise him or seek the help of someone whose advice he would likely listen to; to edify him on his wife’s rights over him, and to remind him of Allaah with regards to his harshness towards his father and the other prohibited acts that he is committing, such as drinking beer and the like. For more benefit, please refer to fatwa 50623.
You are also advised to remember Allaah frequently for it helps you find a source of comfort to forget this abuse. Verily, the remembrance of Allaah strengthens the heart and fosters serenity and peace of mind. Allaah, The Exalted, says (what means): {Those who have believed and whose hearts are assured by the remembrance of Allaah. Unquestionably, by the remembrance of Allaah hearts are assured."} [Quran 13:28] Also, try to preoccupy yourself with what benefits you in the worldly life and the Hereafter and seek righteous companions to help you in all your affairs.
Allaah knows best.
