Plz I need your advice!?

[Canibus]

Am I being silly of do I have a case is what I want to know here.
Me and my girlfriend post on a music forum and there is this guy who slags me
off constantly about being unintelligent and shit. He just winds me up so much right. Well I slagged him back saying well he was ugly. My girlfriend stuck up for him and said that I was being nasty and shouldn't rise to him. Which I agree is true. But I felt very hurt that she stuck up for this person who constantly slags me off and is nasty to me and when I just give him back a little i'm being nasty. And then she tries to talk to him normally!
Am I being silly about this or do I have a right to feel hurt and betrayed. Because when I try to put myself in the situation where someone was to be nasty to her (even if its just on a forum) I just couldn't see myself sticking up for this person if she was mean back to him. I would back her up.

Any advice would be great. Because this happened yesterday and I haven't spoken to her since and I feel awful not talking to her but I feel that I am in the right here. And we are both stubborn and if we don't talk we could just end up not talking again! :o(

Well, Canibus, you know her better than I do. Tell me what you think about the situation, and I'll tell you what I think.

[Canibus]

I just told you the situation. I agree with her technically - I mean morally and all that crap she is right I should just ignore it. But I don't agree with the fact she should stick up for him and it hurts me that she did.

Ok, Ok

Does she ignore you or send short replies to you when she is talking to him? Look, he's obviously trying to steal your woman. Does he know her offline? how long for, if so? how long has he been bagging you? the longer the worse it is-BECAUSE it seems to me that what he is doing is swaying her, and the fact that you feel betrayed proves it. Hey I gotta go for dinner now but I'll be back in about half an hour, if you need to talk more.

No they don't know eachother offline. Its just a music forum. Thats why i'm in two minds whether it is silly to get hurt by this. But at the same time I just can't seem to shrug the idea that her saying I was being nasty and stuff and in a way sticking up for him it is ya know? She wants me to take the moral high ground and ignore him and she just wants to try to talk normal to him to get him to stop. But still ya know if anyone was like that to her I wouldn't try to do that I'd back her up. Ack I dunno

I understand, is there a way to block him? How close are you to your gf? how long have you been together? Can you talk to her about this? Let her know that it makes you jealous. How old are you?
