PM,
If one is in a scenario where they do have feelings for a cousin or have a cousin boyfriend/girlfriend.........does NOT necessarily mean that any humping of any sort is taking place. And the same can apply if one's significant other is someone that is not related. I personally don't think there is anything wrong with liking/marrying a cousin. It's a matter of personal preference. Some people are fine with it....others are not. If it were that bad......it would not be allowed in Islam. But it is allowed in Islam. To each his own. As long as a relationship is successful and healthy, that's all that matters.
If your boyfriend is a family member and you bump into them alot......then wow......that would be one hell of an uncomfortable and difficult experience....to get over. I guess the best thing to do would be to limit contact as much as possible without seeming obvious/rude and try your best to focus on your current partner/marriage and make efforts to move on. .
well she had "feeling" for him 4.5 years. Now thats lots of humping.
Dont tell her to bump into him alot, cuz she has hahahah
