Mostly terrible advice thus far. I was actually in a similar situation about a month ago, but for me it was difficult because I didn't have a girlfriend and admittedly I had been making out with her anyway. Just didn't want it to go any further. What you need to do is heavily play your girlfriend card. If she comments on the weather, say some shit like how it reminds you of how you went to the park with your girlfriend when it was sunny, etc. If she mentions food, talk about where you ate with your girlfriend last and then recommend the venue. Just keep it natural, but casually mention your girlfriend at every conversation topic. She will get the hint that you're really into your relationship. You don't want to be a dick and fuck with a girl's pride. They aren't used to being outright rejected like us guys are and it can lead to huge self-esteem issues, especially if they're already there.You don't consequently want to outright reject her. If it does actually come down to that, just make amends (I know) and make a lot of effort to keep it super cool, as if nothing had happened.

Just buy a fucking printer, it's like 50 bucks nowadays you cheapsake :-P

Date her just before your birthday, tell her you'd like a printer, upon receipt of the aforementioned printer, tell her to fuck off.

Nah, seriously, try to make her aware of how involved you are with your current girlfriend, without embarassing her about her overtures to you, just say during conversations, stuff like, how well things are going with you and your GF, stuff like that.

yeah, and buy a printer..wtf???

ITT: How to correctly purchase a Printer

Dr. Phil and Dr. Joyce Brothers have NOTHING on the relationship experts in this forum.

I dont see the problem tbh...

Just talk to her?
Dont say any maybe, dont promise anything, tell her that you see her as a friend / sister.
Is this so complicated or am i just strange?

You're strange, that's not how you buy a printer. I mean sheesh, you need to go to shop and give them money, not tell them that you're just friends - if you do that, they're going to look at you funny, call security, and you won't get a printer.

When dealing with women, logic is thrown out of window. When dealing with my wife, ive 'looked' and argued to best of my über-logic skills - to no avail. The engineer in my has trouble understanding that 1+1 does not equal 2, but thats the way it is.

After all these years, the only thing ive learn for certain, is that any logical equation has some random modifier N there and that any statement by woman (or -heard- by woman) has this same random modifier added to it.

Men of today are not one bit closer to understanding women, than our ancestors 10 000 years ago.

Just my two cents :)

Have you bought a printer yet?

Actually it depends. It either gets added or substracted - it really depends on whether your statement could be, in any way, shape, or form, interpreted as a personal attack on her, and if it can, the modifier just fits precisely so it is interpreted that way.

Or she might think you're so comfortable around her that you act all casual and stuff.

But yeah, I'm still with my first girlfriend so what the fuck do I know.

Best forum topic ever....

I dont see its really about 'attacking'. Rather, where my instinct is to try to see anything in the most neutral way ('lets think this logically'), my wife forexample mixes her own hopes and fears in to the matter right then and there.

For example, a friend of mine broke up his girl friend recently - my reaction: it/shit happens. my wife's reaction: "Did I cause this my saying A, B and C?' (no she didnt have anything to do with it).

The most classic example would ofcourse be when gf/wife 'asks your opinion' -> and is then hurt when you honestly tell them what you think. I believe, that somewhere deep they know they dont want to hear your opinion, they just want to hear you agree with them :)

Its all stereotypes ofcourse, but damned if they dont seem unnaturally accurate at times..

Well if we're trying to be reasonable about it (hurr hurr) I think it's just females tend to interpret information in a way that seems to be the worst at the time. She gets a call from police about her kid, he/she must have died in an accident, she's informed that you are sick, you are definitely going to die in like 5 seconds, you know, that sort of thing. Yesterday, my wife called me immediately after she heard that there has been an accident involving a tram in our city, because I was surely on the damn thing.

And ... Well, while that's not very rational, it is a damned good defense mechanism.

You could also send her a link to this thread, pretty sure that would keep her away from you.
You would have to buy your own printer though.
