do i love him and should i tell him how i feel?

I met this guy on the internet we didn’t talk on there though he sent me his number asking me to call him, then I sent one back saying "you call me" with my number and that’s all we said on the web.
About 2 weeks later I received a phone call off him the conversation lasted around one hour he lives in London and I live in Liverpool which is 4-5 hour drive. after that we would call each other occasionally once or twice a every few weeks, then the calls got more and more often until we was talking nearly every day we would talk about everything we clicked so well and I felt so comfortable telling him everything, we would also do a lot of flirting too.
We eventually organized for him to come and see me by this time we had been talking for just over 5 months.
I was a little nervous but as soon as he arrived I started to feel more relaxed and we ended up kissing and eventually having amazing sex it felt so right and I was so open and comfortable around him. He only cud stay one night because of work and he went home the next evening.
We continued to talk nearly every day and I think he is amazing he is a wonderful person, if I am upset I will call him and he always cheers me up. He calls me princess and tells me how amazing I am. I always tell him how great I think he is too, we even send each other texts saying goodnight when we are going to sleep but we do still talk about other people we are going on dates with, he didn’t used to until I said I didn’t mind because it never used to bother me but just lately it has been getting to me a little bit.
I know we live far apart but if I had the chance to be with him I would make it work and eventually probably move closer to him, but im not sure how he feels or even about my feelings and im not sure if I should tell him how I feel because I wouldn’t want things to be awkward between us.
im going to go and see him in a few weeks and if I am going to tell him I want to tell him then face to face not over the phone.

WHAT SHOULD I DO I AM VERY CONFUSED??????
