I've had to deal with several of these in the past. It took me a while to realize that the hate was outweighing the love, so I ended up breaking myself off from those people. I don't have too much advice to give, except that you might want to consider weighing the pros and cons of the relationship... If the cons outweigh the pros like mine did, it may be best to end the relationship or at the least, take a break from it.
