I have been friends with this guy since we were really young. We have never dated or been intimate. However we are close and do a lot of stuff together.

He started dating a new girl recently. A couple days ago they came over to hangout and pretty much made out the entire time. The next day he asked if I wanted to come over to hangout. Again they pretty much did the same thing. I just decided to get up and leave. When I did he was like “where are you going?” Then he texted me asking why I left.

Yesterday he wanted to hangout again. I didn’t really want to but decided to anyway. The three of us actually did hangout like normal. However a couple hours into it his girlfriend is like “when was the last time you were with a guy?” I said a few months ago. He was sitting on the couch and she straddled him and started kissing him. She was like “do you want to kiss him?” I looked at him and he was all smiley. She kind of pulled me closer to them. I ended up kissing him a little bit.

Finally I got up and just left. They were both like “no don’t leave.” It was just really weird.

TL:DR - a friend of mine and his girlfriend wanted me to make out with him and I don’t know what to think
