Ok. So there is this guy who very deliberately hit on my GF via facebook. This guy is not the same guy as in my
other thread. It's a completely different person. Anyway, he wrote something very ... coming-on-ish on my GF's wall. My GF told me already the guy creeps her out, so that's great

.
The problem is, I don't know if I should be more protective and/or possessive and tell this guy and others like him to back off. I don't want to make it seem like ... I own her, but while we're together, I'd rather not have other guys sniffing around. If I should be more protective/possessive, how should I go about doing this? I just have no idea about how to deal with this sort of thing. Or do I have nothing to worry about because she already told me this guy means nothing?
Thanks.
