<human>: Can you summarize the given text in a few sentences?

My relationship with my cat has been a bit rocky since I got him about a year and a half ago. He was about five months old, if I recall correctly. He does occasionally sit on my lap, and he has affectionately head-butted me on the face a few times, which I absolutely LOVE. Most of the time, though, he'll try to bite my hand when I pet him and generally does not pay too much attention to me. Even worse, every now and then he will get this look on his face where he flares his nostrils, perks his ears up, and tilts his head, and I know he is going to jump and attack me. It is never very vicious, and I can just walk away, so it is not a major cause of concern for me. However, he does not exhibit this behavior with anybody else who lives in my house. He seems to really have taken a liking to one roommate in particular. He gets excited when she comes home, climbs all over her, spends a lot of time in her room, and never tries to bite her when she pets him. It breaks my heart. I love the little guy so much and I would love to have that kind of relationship with him. Is there anything I can do to strengthen my bond with him?
<bot>: my cat doesn't seem to like me very much, greatly prefers my roommate. How can I strengthen my relationship with him?
