How do I show him I've changed?

You pull away at a first sign of disrespect and stay away

For as long as you keep replying while he is treating you like a player you haven’t changed and he knows.

I think this is very easy. You can simply say something like – I was very excited when you got back in touch, and when I found out you were again close by. I know we have a history of dating thoughtfully, then later more casually. Update on me – I’ve done a lot of work on myself and finally ready to explore something real with someone. Our recent interactions seem to show you’re still interested in just casual with me. So I’m going to take this opportunity to wish you the best as we seem to be looking for different things. Then stop responding to any nonsense, or less than authentic interactions.

98 percent chance he won’t step up or be able to treat you thoughtfully again. If this guy really saw potential with you a girlfriend he would not have led with player moves or talk. But saying something to that affect – lets him know you’re not having it, it’s non judgemental and lets him know where you’re at. If he by chance gets triggered to try and win you after you tell him where you stand – let him try and the first time he acts like a f-boy, drop him like a hot potato

Maybe the brief thoughtful guy was the fake persona, and the cheap player is the true persona. Take him for as he is, not how you wish he were.

Sometimes fake e-mail adresses also have a pic.
But, im sorry to say, the title of your post says: how so show him i’ve changed. The the old needy you showing up because you want to show HIM. By showing up, you responding and wanting to show him you dont want the hook up guy but the attentive guy he briefly was, youre already halfway destroying the good work you did on yourself. Consider this a short relapse. If he is showing disrespect make it clear in actions you dont approve. You dont counter disrespect with slhowing how much more of value you are.
And Yes he problably still thinks of you as easy to hook up with. I would not engage anymore. Some people are like crack to someone else. Stay away from crack

And I agree with Newbie, the fact that you are still engaging with him and hoping he’ll change and treat you better is undermining the work you’ve done on yourself. You want approval from him. That’s needy. He’s not going to change, and he’s not worth your time. Just let this one go and move on to a better guy, and don’t destroy the hard work you’ve done on yourself :-)

I dont think he is a nice guy at all. Fooling around is one thing but to keep you on a leash knowing you liked him a lot makes him a big as/s/hole. But the problem is you. For not knowing what is actually good for you and accepting breadcrumbs. Too bad so many women are affected by this. But you can change. Not for this dudd. Yes he will find someone one day but not you. First you have to tell yourself you do not want a guy that doesnt want you. A guy that actually wants you is the bare minimum of a guy to consider. Then read why men love b*tches. Again not for this specimen but for date and posture practice. Last its more hard word: you need to figure out why you are so deadset on walking into non commital walls.
But really you will be fine. If you leave this guy alone he will fade away before you know it

Hi all,

Just to give you all a final update on the situation. We talked, I asked him what he was looking for with me and he was honest and said that we just wanted a one night stand and that was it. I don’t want that, so we decided to not talk anymore and part ways for good.

Thank your for all your advice!
