My boyfriend of 11 years told me today that he wants to have sex with a 90 year old woman that has been our mutual friend for a couple of years. He is being kind of "pushy" about the subject and I'm very confused about the whole thing.
We (he and I), have not been having a lot of sex because I just had a major surgery that is causing me pain; and I tell him so.
This 90 yr. old woman lost her husband about two years ago.

I went to AZ to take care of my ex-husband that was dying of cancer for 2 months, then he passed away...my ex.

My boyfriend told me that he was going out with this woman (a lot), while I was away.

While my boyfriend and I are having sex.... He tells me that I need to bring the subject up of having 3-way sex with her.

This is so uncharacteristic of my boyfriend, so I'm befuddled and confused.

He's also masturbating almost every day.

I have NO idea how to handle this situation.

Any suggestions??
