pls help me (i need it)

im currently in a long distance relationship with my bf (hes coming home in 3 weeks). i love him and he is amazing but i tend to have a hard time taking in/processing sincerity and i shy away from highly emotional conversations. he, on the other hand, constantly wants to talk about the sappy stuff and how wonderful he thinks i am. i love him and i know he loves me back but its honestly hard for me and not that fun to constantly hear his feelings towards me. im not sure what to do and hes so loving that sometimes i feel like what he says can lose meaning.
