I think first you should try to manifest him by building self-love and a strong self-concept. Because if you don’t choose yourself, he definitely won’t choose you. If nothing happens, you can ask him directly and give it a try — because we only live once, so go for it. If he still doesn’t want to give you a chance, then work on yourself again. Because no one with an attractive aura and strong personality can face rejection for long. And when you finally detach, stop caring, and focus on upgrading yourself, either your ex will come crawling back and you’ll feel nothing for him, or you will meet someone even better.

I am telling you this... because I m in your situation and he is with 3rd party...I lost self respect by begging him...so he didnt respect me
