On Sharing Progress

I made some progress, only a little in photography - found a person on Facebook who wants to collaborate on taking photo and that's it.
Last week, i shared it with my friend in a coffee session because we ran out of thing to say during that conversation, now he keeps asking me how things are going with the model as if i wanted to make her my girlfriend?
I kinda regret sharing it with him because it was me watched video of Dr K that do not share progress, because talking is some kind of venting, my brain will be tricked that the work is being worked on while nothing is getting better. Now, the other thing that i observe is that eventually people will ask you how you are doing which put you in a situation of being pressured - not by him but by you, by the misalignment of expectation and reality. I think the better way is that we will journal it and reread it after some time to see how far we have gone, not sharing with other unless we need help.
Second, gotta be more careful because it also depends on the person - the person that i shared with was a close friend but due to his nature, i know that he asked because he wanted to know certain thing so that he can talk about that with his girl, not because he deeply care about his friend (me). I know this because this is not the first time he actively ask me how i was doing then tell me that he tell his girl the story about that.
Now should i consider if i still find see him as a close friend because if i'm not happy sharing things with him but having to filter out all the personal topics before i could share it to him, he's more of a person that i know rather than a close friend, because for me - a close friend is a person that i could share personal things and not getting judged, a close friend is a true brother that we could rely on, the trait that my friend carries is to reliable to me because he's easy to bend that i don't know how i could trust him in harsh situation, i don't want my friend to breach his relationship so that he could help me out but he will eventually find way to help a brother out, not finding excuse to back off.
