What to do if he's doing the slow fade, call him out on it?

I would still advise you to do nothing and just let it be.
If he asks you out again great but, if he doesn’t there are other men out there too.
Also, if you’re tired of the texts you can simply choose not to respond to them.
Remember this is the early stages of dating soemtimes after a few dates things just end and that’s ok.
In your case this could just mean that there is someone else out there that asks you out in a timeline that works better for you.

Yes your right things just do end but I did what I wasn’t supposed to do and invested, that’s why I’m questioning it instead of letting it be! And I don’t want to be rude and not respond, but the one word messages are driving me crazy, but now I realise maybe he just doesn’t want to chat! I just need to sit back and let it be whatever it’s going to be instead of trying to control it, it’s just harder said than done! Thank you for your response :-)

No need to beat yourself up about it or feel like you are beig rude.
He is not your man.
Take it as a lesson learned.
In time you won’t even be thinking about him.

Stop responding. That will get his attention that he will lose you. If he doesn’t step up and ask you out, you already stepped back emotionally.

right now you have to think like a man, when he texted you are you ok and you texted back hello handsome not good sounds too needy. should of said oh was out last night having a great time didn’t realize you texted. when he says are you ok, you should say yeah fine really busy I have a lot of exciting things happening would like to tell you about it but I don’t have the time now. you should be ending every interaction don’t give him the chance not to answer you back the more un interested you seem the more interested he will be in you. when he said what do you want from me. you should of said nothing I have no expectations and really have none you would be better off its nice to hope but expectations lead to disappointments. ignore some of his text that will get him going right now he is not sure whether he likes you or not but he keeps you there on the back burner just in case making sure you still want him to feed his ego. so don’t feed his ego, keep you life busy date other people tell him things like I see some good qualities in you but I see some bad ones too. say things like you know I thought we could have something good but I don’t think you can handle me im too awesome. trust me watch him go crazy men don’t like to think are not good enough. he will try to prove to you that he is. say things like im so busy that even if you asked me out on another day I would have to decline I just don’t have the time. he will be thinking what is she doing? is she no longer interested in me? etc trust me this should work but if he doesn’t respond favorably maybe he is not interested then why would you want to be with someone who is not interested?

You’re overthinking this. He could be stressed from work or something that has nothing to do with you. Regardless, let him contact you, respond as soon as you can and be normal. Even if he is losing interest (which isn’t clear to me) calling him out on it is inappropriate. Think about it – if you had gone out with some guy a grand total of 3 times and then got busy or were thinking through whether you wanted to continue dating him and he got up in your grill about it wouldn’t you be turned off and tell him to get lost? The bottom line is, you can’t make someone like you who doesn’t but you CAN turn off a man who is perfectly interested by getting needy.

No, don’t dignify a guy by asking him what’s going on or why he’s less available. Just forget about him and go about your life.
