You've said something more important than you realise. Women generally pigeon hole you into what kind of guy they think you are and how you should act towards them. If you're the kind of guy who usually takes women on 4-5 dates before sleeping with them, women are subconsciously aware of that and you are also aware of it too. So unless she is more forward(which is rare), you're waiting until then. From this thread, it's clear getting a girl over early in your interaction isn't something you do often, it's been saved until it's at the point where it's more socially acceptable.
Now I'll share with you how I do things. I'm at the other end of the scale, I move pretty quickly with women. For example, in the past week I have slept with 4 new girls. I invited 3 of them over for the first "date" and the other one I met at a bar about 5 minutes away and had her back within 2 hours. With these girls, I literally sent them my address and said "come over and lets chill" or words to that effect. I didn't ask anything, I didn't try and get them over on some alternative proviso. I feel that as soon as you start attaching qualifiers or reasons to her to come over you're making it weird and I feel it can come across as a little bit weak but it depends on the girl. I wasn't always like this but it came from one particular experience where I had asked a girl to go on a date with me like 2-3 times and she kept putting it off and flaking. I got annoyed and just told her to come over, she did and we ended up sleeping together. Funnily enough, I had another girl come over this week who I didn't end up sleeping with(not through a lack of not trying) but she insisted it just wasn't in her nature "to do these things, the first time meeting a guy"...but remember she still came over and she still snuggled on the couch etc.
So what I think you need to do in this situation and future situations is to pull the pin. Ask her to come over, if she says no you can still move things backwards a step and then when it does come to inviting her over later again, it's way easier because the topic has already been broached. Also as an older guy, I understand it is slightly different and you may want to get to know her a little better first etc. But when it comes down to asking, make sure you're short, concise and act like it's a completely normal thing to request from her. These principles also come in handy later down the line too.
" No reply since then. Perhaps she's worried about the long distance text charges, or really is busy or trying to test my interest etc. who knows? I'm going to wait for her to reach out and I'm fairly confident that sooner or later she will.
