Something I've noticed is that a lot of NVM/LVM will have zero friends except for other women they find attractive. My last relationship with an LVM his "best friend" was in her early 20's (he was 34) and all the other friends he bothered making and keeping in touch with were young attractive women. He had one guy friend he had known since college whom he rarely saw.

Bottom line: be wary of men who ONLY have female friends and/or have very few long term friendships in general.
