Was with ex on and off for two years. We work in the same building, but not department. I see him in passing pretty much five days a week. For a year we didn’t really speak because i called it off because he was stringing me along.
We got chatting one day and I asked him if we could be friends. He said he would like that.
We have been chatting a few times a week. Usually instigated by me.
He will do this weird thing on messenger where he turns his active status off all day but pop it on at 11pm at night and he only chats to me late at night.
I had a big presentation on Monday and he’s not asked me how it went, even though he knew I was nervous about it. He’s kinda blew cold to be honest.
I was hoping we could build up a friendship but to be honest I think I wanted more. I just wanted to see if he wanted it or pushed it.
The fact he doesn’t speak to me during the day and only late at night shows he’s just using me to relieve boredom doesn’t it?
He’s off sick just now with a broken leg and he’s admitted he’s home, bored and watching tv all day….but texts me at 11pm 
I made a decision tonight to not be online at that time and just pack all this in.
How do I handle this? Block and ghost? Have a conversation about it? Just distance myself, I dunno 🤷♀️ but it seems he’s not genuine or interested anyway.
