So, I've been, or had been with my girlfriend for just over a year until she broke up with me because she said if hurt her because I kissed a girl. Now I kissed this girl around 3 months into the relationship. The kiss was not intimate, or meaningful, it was not a snog and was certainly not getting off.
The reason I kissed the girl was because she was upset and panicking over a guy she liked and she said she wanted to kiss him but didn't know how. I had been friends with this girl for 5 years, and I knew how nervous she gets.
So in my efforts to help the situation, bare in mind this was at a party, I proceeded to kiss her on the lips (it was a peck if anything) and then I told her, do that to him and the rest should come easy.
Now she did exactly that and she is now in a successful relationship with the guy.
My girlfriend, whom I told the day after about it, said this upset her, and even though I explained to her the situation, she told me that if I ever kissed another girl, she would leave me. I saw this as a major reaction but had reason. So I continued with our relationship, doing everything I can to make it up to her and show her I was sorry for upsetting her.
Now, recently I went to a party, with my girlfriend, and I was greeting all of my friends with hugs, and the girl was there, with her boyfriend. I proceeded to hug the girl...... this caused quite a stir as my girlfriend ran off very upset. She said that our hug was "too close" and it wasn't anything like friends hug, even though I hugged her the same as every other friend I greeted that night, boys and girls. My girlfriend after 2 days of thinking to herself, broke up with me because she said she couldn't trust me and she didn't want to be hurt anymore. +plus note, after this party I walked my girlfriend home, after cheering her up and dancing with her, she didn't mention anything about the hug again.
So I am asking as a man greatly confused and upset.
Am I in the wrong? And how do I prove to my girlfriend (or ex) that she can trust me and that she will not be hurt by me in such a way ever again?
