If you're looking for a meeting place or a good stop around ½ or halfway between Fort Wayne and Van Wert, you can try Tillman, IN, which is about half an hour east of Fort Wayne, or about half an hour northwest of Van Wert.
Another possible place to stop near the midpoint is Four Presidents Corners.
About ¼ or a fourth of the way, you can stop at New Haven, IN. This is about 12 minutes east of Fort Wayne.
If you drive straight through without stopping at all, the total distance is 41 miles. The distances shown above don't include local roads to get into each town, so if you're planning a long road trip, make sure you factor in traffic and road conditions, rest stop breaks, and interesting detours along the way. If you're in a rush, you can do the trip with zero stops, and your total travel time would be around 43 minutes.
