Why does he text me ?

So my ex and I broke up in January. It was a mutual thing where he decided he wasn’t ready. He was honest with me and always told me the truth. So it wasn’t a bad breakup and we decided to stay friends after that. We didn’t talk at all for about a month, just because I wanted to make sure I actually only wanted to be friends with him and no other motives.

So we text on and off, he takes forever to respond. Like 10 hours lol. Which makes it hard to have an ongoing conversation because I’ll forget what we where talking about, or I’m doing something else at that time.

Like why the heck does he even want to talk though? The way I am, if someone doesn’t want to talk then they are free to leave and I don’t wanna talk to anyone that doesn’t wanna talk back, but I don’t see the point with such late replies.

I talked to my friend about it, and she says I’m just not use to the way guys text. So this is a normal thing right? I’ve never really had a guy friend. She also said he could just be trying to keep in contact with me just to have contact? But again what’s the point? I really don’t know how the male brain works but I’m confused. I want to ghost him because I don’t like it, but I also don’t want to be rude either. What does this mean?
