Not unless you screw up somewhere. There's a big bug-fix on Day 85 for Ashley in the updated version - don't think it's on here yet - will compare versions later. Two really, (1) if you had sex after the Tatianna/Connor dinner and were being good to her you should now be properly on the girlfriend path and (2) she shouldn't acuse you of neglecting her after San Matthews (wrong variable name used).Is Ashley supposed to breakup with MC after that fiasco with Gary and the ladies?
If you want the true girlfriend path with Ashley, find an earlier save around the dinner on Day 68 and backtrack/progess to it (or restart) and wait for the updated version to get here. The Ashley girlfriend fix has been corrected on Day 69 and you won't miss out on a bonking session or two + stats.
