Hello Friend, Good that you are seeking a help here. Yes it hard to handle such harsh truth immediately after marriage. Generally, every marriage relationship will go through one such difference of opinion or habbitual problems or like/dislikes and more. It takes some time to understand each other better and accept few facts and adjust among yourselves. It's better if  both can go for marriage counseling guidance to  open up and get each others expectations clearly understood. It's nothing wrong to consulting a professional as it will help to avoid carrying unnecessary dislikes and emotional disturbance. If both not possible, you should consult to gain your confidence and getting into depression. In that process, you will also find suitable solution to change his perception about you.

Why he is behaving in that manner is all physical , finicial matters are all in alignment. It's very different having a relationship with girlfriends on one end and taking the family responsibilities on other end. Have patience things will resolve definitely.
