I'm considering asking my girlfriend to move in with me

Thank you very much, that is great advice! It is always nice to hear from a women's perspective. I'll feel it out and see how she responds. If all goes well then we can set up a timeframe. You only live once, right?

I think you need to just have a discussion about where she sees the relationship going as well. You obviously want to move it forward but she might not be ready at this point. If you have a discussion about it rather than just asking her straight out it gives her an opening to voice her opinion rather than just giving you a straight yes or no. If you prepare yourself that she might say no then you can move forward from it. She might not be ready now but that doesn't mean she won't be in a couple of months. When my boyfriend first told me he loved me we had only been with each other for 2 months and I wasn't ready to say it back, it was important to me that he understood that and that we could move on and carry on the relationship until I did feel that I could say it. If you relationship is strong I'm sure it will work out :-)
