What should I do? need some advise?

Long story short : there’s this guy I’ve been closed to for 5/6 years. We class each other as friends but act more, do what couples do. We do have arguments like everyone else. So I’ve found out that he’s been lying to me which he explained why he’s done it and apologised. That’s done& sorted.
It’s been 2/3 weeks and we seem to still talk but there’s like no effort. Not being bothered or anything. Seems like we are drifting apart.. which just upsets me. I understand we both need to do what we wanna do etc don’t need to text constantly or anything. Last night I did explain to him how I feel& he said that it seems nice not having to worry to text back or see me bla bla, sometimes it got too much of both of us tbf. So it’s nice to give each other space, I just feel like he doesn’t care and he ain’t bothered. Seems like for him it’s easy to forget and just act normal when that’s not the case. If we drifting apart already maybe it’s easier to walk separate ways.. I just wish all this lies didn’t happen at the beginning as nothing like this would have happened. I don’t even know what I should say. If he sounds not bothered then I’m not going to make an effort because why should i? :( it works both ways.. shall I just leave it block him on everything and try to move on? Or?
