I started dating other people
Hi there. I have no idea what the birthday comment meant, but it certainly does sound like he doesn't want a committment at this time. He could be always hanging around because he doesn't want you to end up with someone else. Almost like he's able to fall back with you if something better is happening for him. Personally, and in my opinion, you should tell him the relationship is over and you are moving on with your life. Then avoid all contact with him. Don't let him string you along like this.
The only way to stop him being ambivalent is to stop agreeing to hang out with him. You are broken up, he says he doesn't want a relationship with you, why are you even answering his calls? Sure he is calling you, he has no-one else around at the moment and he obviously enjoys your company (as long as there is no commitment involved).
What I would do is tell him that he needs to stop calling you because you are broken up and you will not be able to move on and get over him unless he leaves you alone. Tell him you can be friends one day when you have had a chance to fully get over him and you will contact him when that day comes. In the meantime, wish him the best and then DO NOT ANSWER HIS CALLS AND DO NOT CONTACT him anymore.
He will continue to use you for companionship and sex for as long as you allow him/until he meets somebody else. Value yourself more than you value him. Do what is right for you, so that you really can move on. Don't settle for a man that is ambivalent about being with you; he is messing with your emotions whether he means to or not. If he wanted to be in a relationship with you, he would be. Maybe he needs to go cold turkey to realize what he is missing. Tell him not to contact you unless he changes his mind about wanting a serious relationship with you.
Love yourself enough to lose this relationship.
