Does getting to second base with my exes best friend's girlfriend and a coworker make me an asshole?

Alrighty so The ex and I broke up a while back, and just recently, she called me an asshole. Let me start with the beginning. So the exes friend, he hates my guts. His girlfriend and I, we became friends. I went over to her apartment. Several times. We'd always watch movies. Curl up on the couch. Then after a couple days of movie watching, her boyfriend was at my exes grandma's house for Thanksgiving weekend. So the weekend before, I went over to his girl's apartment. We watched a movie, and then, started makin' out. I got to second base :) all touchy-feely (even got to reach under the shirt and grab a hold) and then her boyfriend had to call and interfere with it. To this day, to my knowledge, he still doesn't know that I got to second base with his girl :)

And another story.

When I had a job, two jobs ago, there was this girl there who had the hots for me. She's married. During the mini-fling we had going on, I was all acting like I was going to hold her hand, and would pull away, so one day she just grabs hold of the hand. She'd always ask me for help with her marriage issues.
Then, on our final night of hanging out, even better that it was my 22nd birthday. We went to a burger place. Sat in her car. I held her hand. Her shoulders were hurting. I gave her shoulders a rub, etc. Only used my fingertips, and brought this honey to a bunch of little Orgasms man, just with my fingertips. I didn't even touch her down there, just her thighs. Yet I still got her all moany and orgasmy.

Now, that, is awesome. But, does it really make me an asshole?
