My "surmisals" are based solely on your signature.
You have an older husband, who is approaching 40. You are still young and just into your 30s. You've probably been together about 6-9 years or longer. He's probably gotten into a rut, doesn't help out around the house much. Look's to you as a babysitter. He doesn't do anything romantic anymore: no flowers for no reason, no cards, little thought into birthday, anniversary, or Christmas gifts.
You probably think you've expressed your displeasure with the way things have changed; however, guys don't take hints, sighs, rolled eyes, or martyr actions. We are pretty dense and need to have it showed to us in black and white. However, don't give him ultimatims, don't be his mother. You simply ask him what he expects of you in the relationship, then you can tell him what you expect of him.
