I'm really confused because a few days before that he was saying how much he loves me, wants a serious future, and that he will do whatever he can to make this work. Just a day before the incident he said he would never do those things again and he wants to be with me. I know I can't be with someone who will so willingly betray me. I also know in the past he ALWAYS messages me or reaches out even if we don't talk for a while, and I don't exactly want to deal with that jarring feeling.
Anyway I don't know how to move on or let it go. I'm so confused because of his commitment/feelings just a few days ago, and now he has basically ghosted me? What should I even do? How can I let it go if I'm so stuck on why he would do this?
