Debating ENM

I want to be ENM and make connections with different women, but it seems like monogamous people get a lot more connections. They will date someone for a few weeks, then another, looking for the "right one". It makes being honest feel so naive.

I'm not even sure if ENM is right for me, but I keep having it as a goal when I'm in relationships. I think it's low self-esteem pushing me to try to go back into monogamist thinking, but at the same time maybe that's just what works, and maybe I really just haven't found the right person.

Right now is 3 months after breaking up with my wife, pending separation/divorce. I don't really want to get into another long term relationship. But I don't know how to be casual. I really feel like I need to be with someone else though, I can't stop thinking of intimacy, and like sex would be great but it would likely be missing something that would be there with a closer friend or ENM partners.
