How can I get him to apologize to me?

I don’t know what to do with him but I’d like to suggest “ don’t start the apologizing from your side” if you apologize, he will continue forever like that. let him start it. or break up with him. but if you’re crazy about him, don’t break up with him but the only thing you have to do to make him come to you and say sorry is stay silent and don’t apologize.

anytime we have an argument I just giv him da silent treatment…this could go on for days but I works for me…I won’t speak or even look at him and eventually he will apologise

The other answers you’ve been given here are wrong, wrong, wrong. Don’t fall victim to (yet another) immature relationship. If you want to keep things on the straight and narrow, you need to learn to respect each other, and you don’t do that by refusing to apologize or giving the silent treatment. It’s important to keep the lines of communication open - you don’t have to apologize off the bat, but have a discussion with him … you can each explain what you think is the problem (show respect - wait until the other is finished speaking before you start), then you can work on a compromise to see to it that the problem doesn’t show up again.
