Ok,

I have a few questions, don't answer if you feel uncomfortable about them ok ?

1. Were you 'forced' to marry this man ?
2. Is he natively from UK or Pakistan ?
3. Has he ever physically abused you or sworn at you without good reason ?
4. Have you approached your elders about this ? Talk to as many elders as possible, that should get their attention. There are certain steps you are supposed to take before even considering divorce, it's part of our faith after all. Google it =)

This is my opinion on the matter, so please do not take offense, I don't want to hurt your feelings.

From the sounds of things I'm quite shocked that your parents have married you to such a disrespectful and arrogant man, despite them realising it themselves! What were they honestly thinking, I'm appauled, it sounds like they were trying to simply get rid of you rather than do what was in your best interest.

Of course as Muslims we must respect and obey our parents, but this does not extend to our choice of partner. The prophet himself said this.

The Prophet (pbuh) was once approached by a young woman who told him tha ehr father forced her to marry her cousin to increase his social standing. The prophet said that the marriage was invalid becuase she was forced and that she was eligable for annulment. This simply means that Islam does not allow forced marriages.

I'm going off assumptions here, so forgive me if I'm missing the point. If you weren't forced then I think the problem lies with your actual relationship, I will get back to you if that is the case.

From the sounds of your Isthikhara Prayer it seems like Allah is guiding you towards another man in the distant future, again I'm assuming the dream was accurate. Regardless of everything else, remember one thing, keep your prayers regular and your heart clean and I'm more than sure that Allah will show you the right way =) There is no doubt Allah is always wathcing over you and cares about you.

Do not be disheartened no matter what !
You are in my Dua's sister, I pray you resolve things happily soon.
