I've been thinking about your situation. He is not healthy; it seems like he grew up doing whatever he wanted to. Sometimes women confuse their need for someone with love. The truth is, you don't need him, and to be honest, I don't think you love him. The influence he has on your humor is something you make happen, not something HE makes happen (it is biological as much as it is psychological). Women feel more vulnerable and are more susceptible to feel attached when a man rejects or deprecates her. This is consistent with "assholes getting the girl". Usually even simple statements like, "I had such a bad first impression of you," have this effect on women. You are feeling you need to show your worth to him, and since he does not appreciate you, you try harder. I don't know the details of your relationship with him, but you should try finding a good friend (either sex) to help you avoid this guy at least for a while (a month or two, and pray for yourself and for him). Then, you can decide wisely if it's better to stay with him or bid him Godspeed.
