Oh, I know the feeling -- I've been there, and done that. You know what strengthens you and empowers you the most though? It's when you say to yourself "enough is enough of this crap", "I deserve FAR better", "I will NOT be made to feel like crap again, not ever" and to MEAN IT. Those words said to yourself, even if you have to repeat it every day, several times a day, will strengthen you and empower you to NOT accept anything less than what you truly deserve -- which is RESPECT, CARING, TRUE LOVE, EMOTIONAL STABILITY, and KINDNESS -- and if you're not getting that? Walk away, walk away, walk away, walk away.

Trust me. I've been in your shoes many times over. This works. And it rebuilds your self esteem!!!

He is a nasty human being but if you are not a romantic couple, he is free to post whatever he wants on IG and do whatever he wants including dating or going to parties. I don’t understand confronting him about some girl. As much as it might hurt there’s nothing you can do about what exes do when we leave them. I honestly think it’s better to stop following him or contacting him. I do understand you are hurting but confronting him about what he does or doesn’t do just doesn’t serve any purpose. You can do it. You deserve better
