I think its OK to be pro active in finding a mate. I don’t believe we are meant to be alone. I also believe that you should check your motives. Are you just lonely ? Are you avoiding something and need a distraction? If not, then I would invite him to have coffee or a drink and just talk. Keep it light and try not to have any expectations. I am only sharing my experience with you , I am certainly no relationship wizard. I am currently taking a break from relationships due to NOT checking my motives ( i was avoiding dealing with something) and I hurt someone in the process. I wish you well.
