I think my ex has Relationship OCD, should I tell him? what

I think my ex has rOCD but he doesn’t know about it. I just luckily stumbled upon on a forum that tackles the symptoms and everything said on *mod edit* fits well and solved the puzzle. We just broke up recently, no real problems but his doubts and what if’s about the relationship triggered him to break it off and see if he can develop feelings for someone else. He’s constantly freaked out, confused and rambling. Should I tell him about this? We are on NC now, it was a long term relationship but LDR for over a year.
