I’m starting to resent my fiancé

He has hurt me so badly, and I just want to curl up in a ball and stay there..😢

We’ve been together for almost years, living together for over 5. He asked me to marry him on Christmas of 2017, but now I keep asking when it’s going to happen and he just keeps saying soon. I’ve tried to talk to him about it and I just feel like I’m being strung along and used. I asked about specific dates and stuff and only one time he sat down with me to make lists about pricing and who we wanted to invite but now he doesn’t want to talk about it. He keeps saying he loves me and wants to marry me then why won’t he do it. It’s breaking my heart and my feelings are so hurt because it’s something we’ve both talked about since early on in our relationship and I just don’t understand and feel there is no reason why we shouldn’t be married. It hurts so bad.
