Leave him be. Imagine how you first met. Was it really meant for you two to last this long? Also 9 months may be a long time, but you're still young, have a life to life, things to see and explore, problems to overcome. Stay strong, tell him what you really think, if he doesn't let you speak and you think he doesn't back you up, instead is just being a leech just forget about him. Move on. Cheers to your good choice.

He wanted some kind of support. He is being rude and unappreciative though. I think his mental illness is getting the better of him. You don't just go in to an old group chat you're both a member of to slag the other one off. That is really off. You need to know your worth. It seems like he thinks he can gets what he wants. I don't want to hurt you I'm just telling the truth. One minute he's telling you to leave him alone which you said you already were. The next he wants to sleep with you and says I love you. Then another minute he can cheat on you. As someone once said to me, if you really like someone you don't go hot and cold on them.
