is the spark gone? how can I get it back.

After me and my boyfriend fight, I feel like we don't even make up any more we just go back to the normal relationship, and I want to talk about it, but I don't want to push him to talk about it because he always tries to avoid the talk. It makes me feel like he doesn't care anymore about making up he just acts like we never had a arguement and said hurtful things, I feel like our spark is gone. He use to be so crazy about me and now I feel like my issues are pushing him away, because I can be too much sometimes and I don't mean too.
