i think am the only one who doesn't hate alex here i know he was so mean but i think he was very clear that he doean't want love and give dg a chance to back off but he choose to stay with him . i think i am more angry at dg for being so weak and crybaby (the worst type of uke to me ) dg you should man up or i am dropping this manga

You are not the only one. Like you said, Alex clearly said he only wanted sex. So he is not “acting like an asshole”. He is acting like a person in a purely sexual relationship. Which is extremely common in the real world but not iin Yaoi/BL. As much as DG loves and adores Alex, He is not entitled to a relationship with him. Alex even told him to take it or leave it. And He chose to take it. So Alex IS cold to him. But coldness should be expected from someone who has told you upfront that they have 0 romantic feelings about you.
That said... this is NOT the real world, it is BL, so like everyone’s said DG will run away with his tail between his legs. Suddenly, another attractive Hyung will show up and make Alex realize that he really does care for DG and they will live happily ever after.

Alex made his intentions clear but that does not mean that he is the moraly right here. He used dg's feelings to his own advantage and he knows that. He knows that dg is in love with him and used that to fulfill his own sexual frustration. Also he gave dg a choice between lying about it or breaking it with him, which sounds like a blackmail. If he really wanted, he should break this "relationship" up without giving dg the option. He wouldn't go on a date with him. But he obviously didn't want to break it off with dg. All the other is bs. Of course, I say all this but I still don't dislike Alex.
DG is just desperate. It is annoying but you can just man up. It is a slow procedure. I actually feel that this manga has the right pace.

How did Alex use DGs feelings? Did he or did he not ask DG if he was in love with him, with the intention of breaking up with him if he was? How is Alex in the wrong when he asked DG to be honest and he lied? As you said, DG is desperate. And as difficult as it might be to accept, it is not wrong to want a physical relationship as long as both parties consent? The problem here is that DG lied. And as for the date, if my memory serves me right, he only went on the date because he felt sorry about the whole misunderstanding with the other BJ. I think He is trying to be as nice as he can possibly be to DG. And when I say that, I mean in his very emotionally limited capacity because of his traumatic past relationship.
I think the problem here lies in the fact that they both want different relationships. DG believed that as long as he was nice to him, Alex would eventually fall for him. And that just shows naivety. Alex on the other hand, likes having sex with overly nice DG. Of course, after seeing the raws, I don’t approve of how Alex handled the situation. But not everyone can have a purely sexual relationship.
This is super common nowdays and I have personally experienced it. No matter how much you like someone, and how nice you are to them, some people will never love you. PS: I was DG in that situation, but I left before the real drama started.

Alex used DG's feelings because through them he could get his sexual frustration solved. And questioning DG was manipulative when he already knew the truth. He gave DG a false choice, lie about it or take a rejection and leave. Alex could skip all that and break it up with him at that moment, but no. That is selfish.
I know it is a common thing (not only today) but it is douchy thing to do and all these people that do it, pretend that since they give a choice they are right, are hypocrites, because they just use the false hope of desperate people in love.
And the reason can't justify the date thing. you don't go on dates with your sex friend.
Other than that I completely agree with you for the rest you said. and again i don't dislike Alex. as you said i think he just had limited emotional capacity from his ex.
