@sweetbee Reach out to him for some advise maybe? It can be anything, and you don’t need to take the advise, but it will probably make him feel good that you value his opinion. Do you know his interests and about his profession? End the conversation with you hope to talk again soon, or I enjoyed talking to you, something to encourage him to call or email. There is nothing wrong with outright stating to him you want to try and builder a better relationship if he is interested, and you can gauge by his response if he is happy about the idea. He might say it sounds great, or that he has always wanted to do that, or he might give you a luke warm answer and then maybe it will be more of a struggle or a dissappointment for you.
Is he on facebook? Maybe friend him so there is more contact without you having to directly talk to him, less pressure, and he can get to know you and your personality better.
I think it is a great idea to try. It will either stay the same or get better.
