I agree with all of the above. If overall you have a good relationship and this is the only hang up, you could start seeing a therapist to process some of this. Different people in our lives meet different needs. He may be able to support you on a basic level but be uncomfortable with the deeper issues. It doesn't have to be a deal breaker if the relationship is good and you can get support elsewhere.

I would talk to him about it though. He needs to be supportive. Good luck and best wishes.
