Me and my bf dont talk..is that normal?

I think it's fine, me and my boyfriend talk but not much really. But is your silence comfortable? cause i know with me and my boyfriend it is. Although it is not totally silent. Maybe you are spending to much time together, since you have been dating for 3 years you must know pretty much everything there is to know. Try not to stress to to much over it cause it might make it worse but still try to bring up new things. Even pointless
