Get a restraining order and block him from any form of contact

Ok ppl we don't know the whole story. All I know is that ppl with anxiety issues ten over react even a small issue can seem like something big. No offence intended, but perhaps this is one of those times? Jumping to the worst case isn't always the best solution. Sure if your ex is abusive or something go do what u can to get rid of them. But if this is one of those time your anxiety got the better of u making a small thing worse then I think solving it at a distance would work for u.
