Need your opinion about Pisces Man

Hello everyone, i'm new here.. so I met a pisces man by chance online 4 months ago.. he used to text me, call me a lot and told me he likes me very much.. (in other words he was pursuing me! I didn't like him but somehow I started liking his personality etc.. we live far from each other and have time difference.. but somehow we always found the time to communicate.. We plan to meet next year as our schedules don't permit that this year. He asked me a lot of questions if I would be able to move to his country to have a relationship with him and so on, before he said he has developed feelings for me... I can feel it from the way he looks at me when we video call.

last month he became very busy with work.. he started texting less and calling less.. however he always texts me everyday to see how I am and I try to give him space and not be needy cause I know that is a turn off.. a few days ago I told him that I miss how we were before and he said he understands and he doesn't know what to say.. I said "say the truth" and he said "the truth is that i am busy". then I asked him if he felt the same about me as before and he said it's still the same and if something changes he would tell me. I never got angry about him texting and calling less cause I know I can't pretend anything at this stage.. he is always positive never told me he is busy to text me and uses smiles and emojis when he texts me.

I know that guys tend to withdraw and need their space when they are stressed or busy with work.. but sometimes I'm insecure.. I really want to try to meet him and see what happens next year.. but i'm afraid he will forget about me.

So I wanted some opinions, am I thinking too much? I really don't want to lose him.
