How to avoid this vibe without being an asshole? I love those women and don't want to hurt them, I enjoy their company and value we give to each other. I just don't want them to immediately put me into marriage box. How to clearly communicate that I don't want LTR and that we are enjoying each without putting too much expectations?

"I don't want a LTR" and "not looking for a gf" doesn't work - they hear what they want to hear.

You have to make it clear in the early stages that you are seeing other women.

You can't be the guy she completely depends on "to always be there", because this triggers "make him exclusive" feelings in her.

Here's some tips:

• Don't pay. Always avoid the provider vibe, go halves on everything.
• Don't agree to the next time you'll see each other straight away! Leave a gap....at least a few days, ideally more... and then negotiate a time to meet. Be busy for a few days if necessary
• Don't answer her texts straight away. Not always same day.

Closeness is good, but then you need some distance. This keeps her chasing, maintains your value, and doesn't make her feel that "she's got you, she just needs to make it official".

Don't flip that switch of reliability, providership, emotional support and always being there when she wants you.

You'll lose some girls earlier, but you can maintain FWB status for YEARS if you do it right.

Let them talk about it, all they like. Maintain your frame, and be non-committal.

They are adults and can make their own decisions. As long as you don't lie to them then you've done nothing wrong. If they were really after a LTR then they would let you know right from the start.

The actual reality here is that they're playing mind games with themselves so that they can enjoy being sluts while pretending that they're looking for an LTR; it's intentional ignorance as solipsistic ASD. And there is nothing wrong with cooperating with them on this.
