Some people probably think I'm nuts (but don't say it to my face), some admire me (and say it to my face), some may feel threatened by it, but, generally, I've had positive experiences dealing with people. Probably the most uncomfortable part is their thinking they have to accomodate me, and me knowing that they have to accomodate me. I don't feel preachy or righteous at all, because I made this choice for me and not for other people, and I don't judge them for making a different choice than I am. The good part about coming out and saying you are veg is that some people are really interested in cutting down their meat consumption, even if they don't want to cut it out, and you can share recipes and information.
I had some awkward times at the beginning, because I also did not say I was veg, just that I didn't eat meat. It is much easier for me now.
I don't see anything wrong with the way you are doing things now. It sounds like you don't want to eat meat, but don't want to publicly commit yourself to being vegetarian. Why not leave things as they are? But, I wonder, if you seriously don't want to get served meat, and you don't let others know about it, you may repeatedly find yourself in situations where you are wondering how you can get around eating the meat that is on your dish in someone else's house, meat that your host has specifically and specially prepared for you.
And never mind what anyone else thinks about your GF influencing you. Basically, it really isn't any of their business until and unless you decide to explain yourself to them. Let them think what they want. (They will, anyway.)
