Sounds like a toxic work environment and at an excessive commute. Perhaps it would be best to distance yourself from it. As several other HNers have noted, make sure you leave on the best possible terms for yourself. Being forced to resign is a sign that they know that they are in the wrong. Typically when on probation dismissal is not an issue, so why the manipulations? Seems like there is more to the situation than you able to determine. The "personality conflict" is strong hint.
