You aren’t good friends in any real sense. You are digital pen pals.
She isn’t just suggesting you and she meet for a coffee, the usual means of meeting for the first time to see how people get along in real life, but wants to bring her family along into your space for a whole week. It’s too much.
Think about people who do internet dating. They often chat through text messages and phone calls for weeks or months before they meet. When they do eventually meet up, there’s a good chance they may be disappointed with the real thing. Few would ever organise a weeklong holiday before ever meeting.
True this isn’t about physical attraction and sexual chemistry but you and your partner and she and her husband, four people who have never met, two men who have never communicated at all, will all have to get along for week.
On too many occasions, I have committed to spend a week with people I thought I knew well and couldn’t wait for it to be over. I am sure I am not alone in that.
Add into the mix that you and your partner need to be getting on with work while they may want to be entertained more than you have time for is going to be a strain.
You have been chatting to her for five years and may have told her all kinds of things that you would not wish discussed in front of your partner and her husband.
After six months of suggesting meeting and nothing concrete arranged, one would think she would have detected your lack of enthusiam - unless you have been sending mixed messages.
Some options.
• Suggest a child friendly campsite in the area where it would be more suitable for them to stay with more things for the GC to explore safely. Ask them over for an early supper towards the end of the week so you all have enough to talk about, what they havae been doing, for a couple of hours. The children's tiredness would be a good excuse to bring the evening to a close.
• Same thing but you pop over to meet them.
• Arrange either but without grandchildren in tow.
• Arrange to meet her for coffee somewhere equidistant.
I’m sure she will be just as nervous about meeting you as you are her. That last seems far the most sensible thing to do before committing to anything more. Either or both of you may decide that’s as far as it goes.
The fact that you have been chatting digitally for five years or more without meeting suggests to me that this is all it is ever going to be be and should be. OTOH it may be the start of a real friendship. Start with coffee.
