What would his expectations be of you? Marriage is something that didn t work for my ex wife and i. Couples can make the most wonderful vows and promises to one another and that s real nice, even create fantastic memories. Ultimately though, if there is a major difference of how you both view the world, then it may not be a fairy-tale marriage. Are you being selfish? No,not at all.Is he being selfish hoping you might convert to something you have no belief in?No, he has his beliefs.He is wrong calling you selfish though for being who you are and standing by your principles. Live and let live. My own opinion, you two are ultimately not happy marriage material. You are two very different people. Talk, and end on a good note. Hope this helps, but i think you already know the answer. stay true to yourself and be happy.
