If he went a few months without talking to you abruptly the chances are he really isn’t interested. Or maybe he was so hurt by what you did that he just did it to spite you? But i don’t think i’ve ever heard of someone forgiving someone and then doing that? So he’s most likely not interested anymore and probably thinks he can do better. It’s up to you if you’re gonna fight for him or not, but he’s probably not going to be interested unless you show how determined you are.
Then at least then he has the chance to tell you exactly how he feels and you will know where you stand.
