Can an obsessive guy be faithful?

If he was obsessed with having you and wanted you really badly, would he before faithful than guys who aren't obsessed?

As with anything, it depends on the individual's personality / character and morals. I guess it also depends on what attracted him to you in the first place.

As a rule of thumb, if they were in a relationship and became obsessed, then yes I would say then they're more likely to be unfaithful... but again, that would depend on other multiple factors.

He wouldn't be any more or less faithful than any other guy. Or, at least, this wouldn't be the reason why.

Asking for a friend?

Yes, often they are as faithful as a devoted pet animal who never leaves their favourite person's side and can almost be mistaken for their shadow.
Personally I'd be more worried about an obsessive guy turning very controlling, paranoid or violent during the relationship.
Then into a crazed stalker type after the relationship has ended.

Why would an obsessed person become unfaithful?

Sorry, perhaps I should have been more specific.

What I meant was if they were previously in an existing relationship, and they became obsessed with you... and then left their partner, then IMHO, they would be more likely to stray.

It's the same logic as when those having an affair become a "real" couple... what's to suggest the same thing isn't going to happen a bit later on down the line?
