Don't want a wedding anymore...

Jill • Mother of a handsome 9yr old boy. Currently TTC. Living life enjoying my family!
So my fiancé proposed to me on his birthday last month March 11th and my mom passed away 4 days later March 15th. It was the hardest day of my life as I'm currently 36 weeks pregnant. It was so hard trying to not stress myself into labor. Well the other day my fiancé was talking about possibly having our wedding at the Westin and I immediately cut him off with a tone in my voice saying I don't want a wedding anymore. 
My mother and I had my wedding planned ever since I can remember down to who I wanted my dress by. Now that she's gone I can't imagine having one without her. I felt so bad for reacting the way I did because the look on his face was like he was just so hurt. I don't want to be selfish and take away from something he's been wanting because I'm hurting. 
I don't know if it's because it's all so fresh or if I'll never want one but as of right now I rather elope than to have something I can't share with my mom
