Hi - I just wanted to say, it's completely natural to worry about what your LO eats. Everyone does it.
Having said that, though, fruit and veges actually contain very similar vitamins, minerals and other dietary requirements. The main difference is that fruit has more sugar - fructose - which is both good and bad.
So, I'd say, keep offering fruit, and try lots of different things: canned, dried, fresh, pureed, not pureed, juice, etc. And offer the same things multiple times, because one day he might just change his mind. (Just like what they love one day, they won't touch the next, so it goes that what they won't touch one day, they can't get enough of the next).
Probably you'll eventually stumble on some fruit he likes - but if not, don't worry. I'm sure you're doing a wonderful job of making sure he has plenty of fresh food, and he'll get what he needs regardless.
(BTW - bear in mind that some things we conventionally call veges are actually fruits: e.g. tomatos (Ellie love the tiny grape ones), avocado, cucumber, capsicum/peppers, zucchini. Basically, if it has seeds in it, it's a fruit. So he may be eating more fruit than you think!).
All the best.
