Talking phase ...

Hello, How long should an online talking phase last if we genuinely like a person.. but have never met in person .. its been 8-9 months of being good talking friends... Idk .. should i just get off this feeling and move out of it.. because this was the first time in my 22-23 yrs of life i caught feelings.. so i thought it would feel special na.. i just overthink a lot maybe .. And convos have become very less also so just a lil rant..
