Open Question: Is this an instinct or just wanting her back?

[feedcrawler]

sorry if i spelt insticnt wrong or whatever but my GF broke up with me and im fine as long as shes happy but today a guy was getting in her face and i saw it happen and i went over and about broke his neck... she said it took 4 BIG guys to get me off of him... is it an instinct to protect a girl wheather she left you or not? we are still friends and she knows about my Foot Fetish and she is really nice about it.
