<human>: My girlfriend and I have been dating for 4 months now, and she's perfect. She's smart and pretty, sarcastic, and knows when to take me down a peg. She's the perfect person for me and I say that wholeheartedly. 

I recently realized that I get jealous and overprotective easily (I try to keep it locked down and it's been working so far). I even told her of my tendencies to do so and she told me that we should try to work through them. I looked at other posts here and I think it's because I'm really insecure about myself: physical appearance isn't great and I can be obnoxious sometimes.

I guess my question is how to be less jealous and overprotective, or be less insecure about myself. I'm considering going to the on-campus therapist just to get his/her opinion on the issue.

Can you condense the text into three sentences or less?
<bot>: How do I be less overprotective/jealous with my girlfriend, and is it a result of my insecurities?
