I feel like my bf and I don’t talk as much as is normal, advice?

So my boyfriend and I have been dating for about a year and a half now and he’s super funny and sweet and I love him to death❤️

But we’ve recently noticed that once we get passed the usual “how are you”s “how was your day”s and all the usual recounting of the stuff we did that day, we seem to struggle for things to talk about and it can sometimes just be us sitting there in silence

It’s better when we’re actually face to face, but I feel like there are a couple points where it’s just quiet. It’s worst when we’re on the phone, sometimes having long long moments of silence.

This is my first successful long term relationship and I’m really afraid of messing it up, I love him so much. Is this something that’s bad or harmful to a relationship or normal? Is there anything we can do to try and fix it if it is an issue?

Some advice please?
