I think open communication with your husband is important. If you do tell him, make sure you do it in a non-confrontational manner and using 'I' statements. Example: Maybe I am totally offbase, but sometimes I feel like you are trying to make our son love you more than me.
Or after he does something specific, you can tell him "When you handled 'that' 'that way' it made me feel like you were trying to 'make him love you more' (or whatever else). Chances are he has no idea how his actions are coming across as hurtful towards you.
