The reason for the breakup was mainly due to incompatibility and mental illness. It had nothing to do with our feelings for each other, we just knew we were unhealthy for each other so we had to end things. We dated for 4 years. I haven't heard from at all since we broke up last week. It's just hard to think that after 4 years together, it's so easy for him to cut me off cold turkey. Does this mean he didn't actually love me as much as I thought he did and that it's out of sight, out of mind for him? I have been secretly hoping to get a text from him this entire past week but nothing came.
