Forget those people who have no experience in this. Marrying a Qatari is possible. Where there's a will, there's a way. I am a Qatari, and know a few Qataris who are happily married to western women. My dad is one of them.
Of course, like in any country there are a##holes who cheat, beat, and look down on women. I grew up in the States, so no need to debate with me on this issue.

The most important thing is to see what sort of lifestyle your potential future husband is living. We don't need to talk about love, as people fall in and out of love all over the world.

If you are marrying someone who has a similar lifestyle to yours, has a fairly open minded family, is a man who does not fear others' opinions, and does not expect you to be someone you are not, then go for it.

The problem arises, when he expects you to live a lifestyle that you are not comfortable with, is easily manipulated by others opinions, and has a family who would never accept you. If that is what you are faced with, then forget it, as it will just create a lot of tension in the long run.

Ultimately, take your time, and really pay attention to these things, and then make your decision.
