<human>: I'm a senior in high school. I know it doesn't seem like I've had a lot of time to date, but in the time that I've had I've noticed a pattern. 

Every time I try to form a romantic relationship with someone, I begin to resent the person. 

When the crush develops, I'm really excited.  I like her a lot, I get butterflies when I see her, etc.  I'm really enthusiastic about her and finding out she likes me back is usually like a dream come true.  Then there's a small amount of time that's amazing, where I can feel something developing between us, and I remain excited about the idea that I might be with this girl. 

But after maybe a week or two of that, the excitement fades and I'm left with resentment.  I don't like to see her, I don't like talking to her, I'm no longer attracted to her, and I definitely don't want to be with her.  It happens every time I try to form a relationship.  I've pretty much avoided dating in High School because of this, but the five or six relationships I've attempted have been train wrecks. 

Is there any way to overcome this? Or am I destined to be a reluctant bachelor until I die?

Can you give me a shortened version of the text?
<bot>: How do I get over resentment I feel towards a girl I used to like when I'm in a relationship with her?
