I want us to get our own place but my husband refuses; what should I do?

Firstly: 

One of the rights that the wife has over her husband is that he should
accommodate her in separate accommodation that is appropriate for her,
whilst paying attention to the husband’s financial situation. The husband
does not have the right to force his wife to live with his family, whether
that is his mother or his sisters; rather what he is obliged to do is to
give her separate accommodation of her own. 

Secondly: 

Our advice to you is not to rush to go back to your family, and to have a
calm discussion with your husband, explaining to him your need and your
daughters’ need for separate accommodation, and speak nicely to him, so that
this problem can be solved in an atmosphere of mutual understanding and
bearing in mind that which is in the family’s best interests, far removed
from tension and disputes. 

Be
certain that your good attitude will never be lost with Allah, and you will
find good results from it in this world and the Hereafter, by Allah’s
leave. 

Thirdly: 

With regard to seeking divorce or separation (by talaq or khul‘), this is
not an appropriate solution for you, especially as you have children
together. What wrong have they done, to deserve to live far away from their
father or from their mother? 

Moreover, what will their situation be, if custody is given to you or to
him? 

Think long and hard about that, and give it a great deal of thought, and be
rational and wise, avoiding emotions such as anger and frustration. 

What we advise you to do and urge you to do is to stay with your husband and
be patient with the way he is with you, until Allah grants you relief and a
way out. Perhaps Allah will open your husband’s heart to that which is good
for him and for his household. Try not to involve your parents in your
problem with your husband, especially since they live far away. Give them
the impression that your situation will soon be resolved, by Allah’s leave,
and that your circumstances will improve, so that they will not be anxious
about you and your situation. 

Our advice is to be forbearing and patient, and to continue trying to
convince your husband of the importance of having your own place. Remember
that a person may hate something, but it is good for him, as it will bring
him a great deal of reward, expiate his bad deeds, and serve other interests
which he may be unaware of at that time. 

Allah the Almighty indeed spoke the truth when He said (interpretation of the meanings): “…it
may be that you dislike a thing which is good for you and that you like a
thing which is bad for you. Allah knows but you do not know”
[al-Baqarah 2:216]. 

According to the famous hadith of Ibn ‘Abbas, he said: I was riding behind
the Messenger of Allah (blessings and peace of Allah be upon him) and he
said: “O young boy, shall I
not tell you of some words by which Allah may benefit you?” I said: Of
course. He said: “Be mindful of Allah and He will protect you. Be mindful of
Allah and you will find Him in front of you. Acknowledge Him at times of
ease and He will acknowledge you (and help you) at times of hardship. If you
ask, ask of Allah; if you seek help, seek help from Allah. The Pen has been
lifted with regard to what will be, so if all of mankind wanted to benefit
you with something that Allah has not decreed for you, they will not be able
to do it, and if they wanted to harm you with something that Allah has not
decreed for you, they will not be able to do it. Know that there is a
great deal of good in patiently bearing what is disliked, victory comes with
patience and relief comes with distress and with hardship comes ease.” 

Narrated by Ahmad (2803) and others; classed as saheeh by al-Albani 

Finally: 

Supplication (Du‘a) is the weapon of the believer, so offer a great deal
of supplication, asking Allah to guide your husband and reconcile between
you. 

We
ask Allah, may He be exalted, to enable you to do all that is good and to
make things easy for you. 

And Allah knows best.
