think wife is cheating

My wife started giving a coworker rides to and from work everyday. What got my attention was that she started calling me three times a week to bring something home for dinner. She gets out of work at 3 pm and I get home between 6:30 and 7 pm. The guy she is giving rides to is only 15 minutes away from work on the other side of town.

I am 49 my wife is 39 we have been married for 18 year. We are like every other couple we have are ups and downs but always work through them together.

What I know about him! His name is Tyrell and he is about 30. They have worked together for eight years, but it is only in the last six months to a year that I have learned everything from hearing her talking about him. I know he has been in trouble with the court over support for 4 children he has, all with different woman. He wrecked his car and thats why my wife is giving him rides
