Communication Issues

I've been with my boyfriend for about a year and a half now and we've said we love each other a fair few times, but it's always been over text. I feel like whenever we discuss anything really important or serious (or any problems with our relationship), it's usually over texting and I'm not sure this is very healthy for our relationship.
Any ideas on how I could fix this? I've never been very good at talking about serious things in person and I think he is a bit the same.Â
