Search Results: keeping him chasing

I dated this guy, he dumped me, said he freaked out. Then we had an on/off relationship; he kept jerking me around (being friends, then hooking up again), and I got fed up. I cut him off, unfriended him on every social media account, except he still follows me on Tumblr. Since then, I've calmed down and I'm pretty much over him, but I'm debating whether I should bother being friends with him since we did have fun times together. I texted him a couple weeks ago, light stuff and he responded to all of them, but he didn't initiate any. I haven't texted him since then (over a week). I asked him if he wanted to catch up sometime and he said "yea but I'm pretty busy this weekend, maybe next week" and I told him I was also busy, and I'm on vacation that week. To which he responded "we'll figure it out". So I left the ball in his court, but it's a tad frustrating cause I feel like I'm the only one putting in effort to salvage things. Granted, I ignored his texts when I cut him off, and he said he was keeping in touch with me but wasn't sure if I wanted that.

When I get back from vacation, should I ask him if he wants to catch up again, or just leave it in his court? I don't want to spend energy chasing him down, and I don't want to seem like I'm trying to get back together with him either. Basically I don't want to be a fool/desperate. Not sure how to go about this, or if it's just something I should just drop.

To add, he was the one that asked to stay friends, I responded by telling him I needed to get over him since we want different things; I still don't know what he wants, he's vague. When we were hooking up, I weighed heavier (5'6, 145lbs), now I'm 125lbs and feeling a lot happier/confident/sexy. When I was bigger, I had self-esteem issues. If it doesn't work I won't be bummed about it.

TL;DR: Guy dumped me, we hooked up (on/off), he asked to be friends, I cut him off. Now, I'm trying to reconcile, but I feel like I'm the only one putting in effort.

Many guys say this a lot, that they're not ready for commitment, have commitment issues, not ready for a relationship, etc, and I'm wondering how true it is. Personally, I think it's a line. I think when a guy meets a girl he's crazy for then it just won't be a thing. My friend has been chasing after this guy now for months, and he has told her he isn't ready for commitment but loves her. He only sees her like once a week if he wants, and there is always sex of course. He was caught talking to another girl on tinder and that's when he apologized and said it was bc he isn't ready for commitment but likes her a lot, and it has nothing to do with her.

I called BS on that. I told her he may like her and appreciate her company but he is not in love with her, and so he is keeping her until he meets a girl he does fall in love with. Am I correct?
