My GF and I live about 50 miles apart and only see each other at weekends - 95% of the time at hers.. - One of my oldest friends lives a few miles from her - so, one weekend in 3 (or so) I meet him for a quick beer en route to hers - arriving anytime between 7.00 and 8.00 (an hour or so later than if I went directly. - whereupon we spend the whole weekend together (without fail) - with me leaving around 8.00 sunday night- she increasingly seems to resent this..? - AIBU..?
