i have OCD and i know it has been very hard on my husband, though he has been very patient and kind. (things are better now).

your friend may be feeling embarrassed. i've been really embarrassed and ashamed throughout. people tell me not to feel this way, it's not me it's my brain chemistry, etc. but all the stuff i put him through, i know from the outside it looks like silliness or selfishness, and that makes me think it is, even though i (partly) know better.

anyway you're justified in distancing yourself, absolutely.
