Its only been a month.
1 month is not a long time. At this point of the relationship you 2 should be out having a good time and a good laugh together. Not worrying about expressing feelings for each other. It takes time for feelings to go grow, id say after 3 or 6 months at least.
Forcing the opposite to what he wants will only push him further away!
You said yourself he has been screwed in the past by ex gf's, so don't push for commitment.
