I'd really like to say that I wouldn't care and that I'd mover on easily without creating a huge scene; but I'd be devastated. I'm an extremely Loyal and Trusting person (in general) to a very few; so if my Partner would cheat on me, I'd succumb to Depression. Yeah, the impact people (in general) have on me is THAT big.
Hmm .. Well for me, I amor the person so much so my brain can't accept the idea of seeing him with another person .. I mean every time I just think about the "cheating" thing my coração hurts so much & I start to do anything that can make me forget this idea, I trust too much but sometimes this too much hurts so much. So no I don't think so :s
