Vehement opposition to relationships?

There has been no time in my life that I can remember where I had a positive feeling towards romantic relationships. I respect relationships with parents/siblings, but the thought of being in love still makes me to this day SEETHE with anger. I can't talk to people about love/relationships without getting into heated arguments, and sometimes I cause, uh...damage to surrounding things. Glasses, plates, lamps, drywall that gets punched, basically anything that I can throw or break. I really don't like being like that, I feel as though someday I'll end up hurting somebody over a stupid argument. Mind you that I had a great childhood with very loving and supportive parents. Though they would poke fun at me, saying that I would change my mind. That was my one pet peeve, not being taken seriously. My question is why do I harbor these feelings? It doesn't seem that I had a hard life to hold a grudge against. I'm not looking to change these feelings per say, b/c I like being single more than anything else in the world. I'm also a non-conformist by nature I'm just curious as to why I have such strong hatred towards love/relationships. Is it possible to be born without the "romantic love" characteristic?
