Search Results: boyfriend bites me

So I've posted already about my boyfriend talking to his ex of 10 years and how she cheated on him twice.
Lately he's been talking to her a lot and even saying suggestive things like "You were looking so good I wanted to take a bite" when they talk about their past IN FRONT OF ME.

I visited him the other day and found him facetiming his ex, and he didn't freak out or anything but just kept talking to her and making me wait.

WELL TODAY
I visited him in the morning so we could get breakfast and he was still asleep. So his mom said I could go wake him up and when I walked into the room he was asleep in front of his laptop and his ex-gf was on the other line asleep.

Don't normal people just say "i'm going to bed, bye."
He falls asleep with her on the line?

I don't like it and I'm afraid he really still does have feelings... lately little things are adding up and it wasn't like this before... what happens when she comes home in the summer from med school and they're only like 2 miles away from each other...

We were sitting in the car and I was on facebook and he wanted to talk about his day.
I was tired too and just kind of out of it so he called his ex-girlfriend.
They dated for like 10 years and she cheated on him twice... frankly i dont know why they still talk (I posted about them earlier this week).

Anyways, he was just complaining about his day and stuff, but their talk quickly went into their inside jokes and stories. Soon it got into a story of when they were in bed together and she was making fun of him for drooling and snoring.

And he said, "Well maybe I was drooling because you were looking so good and I just wanted to take a bite" but then he was quickly like "well anyways..."

It just felt rude and made me feel unsure... what do you guys think? Does he still like her maybe? I was in the car with him for crying out loud, how do you talk about how you were once in bed with an ex?
