Is it ok for my Boyfriend to spend time with his Ex lover of 3 yrs who he now claims that they're only good friends and no emotions are involved?....

It depends on how MUCH time he spends with her and where. Is he willing to introduce you or does he seem uncomfortable about it?
Is he leaving you out of things a lot lately and making excuses about where he was?
I don't see how no emotions are involved. Even if they are "just friends", there are a lot of shared memories, and a lot of those memories involve having sex.
I woulder how he would feel if you were hanging around an ex. I would HOPE my guy would say: "I don't like it".

I'm sorry for those who do not agree with me ....but h*** no! This guy is seeing his ex LOVER...regardless of a friendship he has probably seen her naked..thats insane..

but if you trust him that much then good for you

I would say no!! I'm kind of dealing with that myself. He said they had always just been friends, come to find out his family told me otherwise. Since then I told him no more!! He doesn't have kid's with her so I feel there is no reason for him to still talk to her.

Do they have children together? If so, then yes.

It's a bit more dicey if not.

On the one hand, they were, and apparently are still, friends. Do you want you tell you bf he can't spend time with his friend?

On the other hand, I understand your worry completely. However, do you TRUST your bf? I would say "no", otherwise you wouldn't be asking about that here. If you don't trust him, then why are you still together? and If you DO, again, are you going to tell him he can't spend time with a friend?

You MIGHT suggest that you have a problem when/if he spends time with her alone, and you'd prefer he not do so. Not that you don't trust him, but it makes you uneasy. If he's gong out with friends, and she's in the group, you won't worry so much.

Something else you could do, is to try to become friends with HER. It DOES happen, but it's less likely that a girl with mess around with a friend's bf.
