Be nice fellas/girls the "dating" protocol or what is obvious doesn't seem to obvious to me.

Anyways, recently I've been talking to multiple people and usually after the 2nd/3rd date they ask or find out through social media, me not responding, etc. that I'm hanging out with others. I'm genuinely not trying to hide & when asked I try to be as transparent about it. Only if they ask ofc I'm not out here spilling everything.

The conversation typically starts from the girl being jealous or kinda hurt by the idea (hope im not projecting), ofc if they did the same I would prob be too. Anyways I've got it twice where they usually hit me the "I don't want to be anyone's option."

It always gets me feeling weird, my response is typically along the line of: We just met but I do want to keep seeing, interesting in you etc.. and it takes a couple minutes for the girl to understand.

I'm trying to be ice cold about it, because for the first in my dating scene im genuinely exploring my options. I don't care that they know I'm seeing multiple people, but I also want to be empathetic to their feelings I just hate feeling the guilt they try to put on me.

What are some good liners for this?
