For whatever reason he seems like he is not engaged in your friendship any longer...Life continues on....If this were me..and I felt this dissappointment again and again...

I would just tell him regretfully his repair shop is out of the way from your place of employment and maybe another time...And I would not contact him again and hope for the friendship that he would contact me..and if not...I would just keep living my life.

Everyone is in our lives for a reason, a season or a lifetime...this was a season of your life..take what you learned from the relationship and use it going forward.
