my fiance’s therapist told him to take a break from me and put our wedding on hold

i cant stop crying and i just need some advice. my fiance (we have been together 5 years) and i have been having a few issues mostly with my OCD. I was recently diagnosed and although i have had severe issues the last 8 months, i was diagnosed in december and have been seeing someone weekly with some improvement. turns out my fiance has been struggling with this and thinks our relationship isn’t working and went and saw a marriage therapist by himself. the therapist had him write me a letter and my fiance emailed it to me and told me he could not speak to me for 4 days as per his therapist’s advice. i asked how a marriage counsellor could tell him to take such a drastic step without ever evaluating my half of the story and i told him that id prefer we worked on a solution together instead of a unilateral one. and he said he has to ask his therapist if that is ok. is this unusual? i see my own therapist and im having trouble with how many directives my fiance has gotten
