im starting to have ugly thoughts that he dumped because he already was seeing someone else i feel terrible.
He could be, also could explain why he blocked you on social media. But it's also more reason to move on. Some people are a**holes, you shouldn't feel bad about it. He could have used the fight as a way out, don't blame yourself. There was a guy yesterday asking a question about stringing along his girlfriend, so he'll have someone while he date around and find someone new, so it happens.
