Romantically, best friend, or just casual friend?

[amma]

There is a guy, an old acquaintance of mine and now we become friend. i really don't know is he like me as a casual friend, best friend, or romantically like me even though we don't have future. We live in different continental, very far apart, and we are very busy. Maybe we will not reunite at least for the next 5 years and many things happened in 5 years. I might be married with my boyfriend, he might be meet someone else.

We were talked much in FB messenger everyday in our first two months, he was available every time i chatted. But these last three months he seems suddenly busy, may be it is not about me, or may be it is. I was mad because i was too needy, i thought he tried to reject me and we had fight, but he said he was fine. Sometime he spare me time to chat but never that intense anymore. He was called me Smarty or Baby but now he call me KID and Dear, i always called him pineapple. In very scarce time he will chat me first, showing his works, his baby niece pictures, his sister. But sometime he didn't reply my long messages at all. He is still nice, sometime he post some of our inside jokes on his wall for me. when i said i miss him, he said it is good, but not said he miss me back, but he spare me quite long time to chat after that. Last time he didn't answer my long messages, he said that he is too busy and need to focus on something and didn't ignore me on purpose.

I am just really curious, guys. What is exactly in his heart/mind? I will be very happy if he has romantically feeling like i do, but I quite honored if he think i am his best friend. I am sure sometimes he flirted like romantically involved even flirtation is very perceptive, but sometimes we talked and laugh about our sex preferences and stories like we are buddies. I don't want to have over romantically feeling to him if he is not. I want a balance relationships with him. I will be his casual friend if he sees me as casual friend. So guys, please give me insight what do you think he sees me, romantically, best friend, or just casual friend?

5 years is a very long time to wait for someone. I would say, continue to live your life, meet new people, go out, because he will no doubt do the same.
Judging from how much personal information he has shared with you, you are dear to him, You might be his best friend. But the easiest way to figure it out would be to talk about it with him (not the best way, but the easiest).

i always called him pineapple

LOL. Why you called him pineapple? What countries are you both from? How old are you guys?

I understand why you want to wait 5 years. I really do. But you have to try busy as possible. Cause you will suffer if guy will be busy but you not.
Your long messages shows that you need him more than he needs you. Its just natural that one who is most needy write longer messages. Facebook is good but have you tried talking on skype?

I think he sees you as casual friend now. What you can do to make things more interesting is if you write him every day then start writing every second day. Or maybe even every third. Also good way how not to be needy is don't write longer messages than he writes.

I am busy too for sure. he was writing much longer than mine. That is why i wrote long messages. I've tried chatted every third day, but i kind of lost interest and feel so distance. I dont like it. May be i love the idea of falling in love with him. I am in 10 years relationship with my bf, everything is okay, and i still don't want to married yet
